SINGLE-CHIP LI-ION AND LI-POL CHARGE MANAGEMENT IC FOR CURRENT-LIMITED
APPLICATIONS
1
FEATURES
DESCRIPTION
•
Designed Specifically to Work With
Current-Limited Wall Supplies
The bq2420x series are simple Li-Ion linear charge
management devices targeted at low-cost and space
limited charger applications. The bq2420x series offer
•
Ideal for Low Dropout Charger Design for
Single-Cell Li-Ion Packs With Coke or Graphite
Anodes
integrated
powerFET,
high-accuracy
voltage
regulation, temperature monitoring, charge status,
and charge termination, in a single monolithic device.
•
•
Integrated PowerFET for 500 mA
Integrated Voltage Regulation With 0.5%
Accuracy
The bq2420x is designed to work with
a
current-limited wall-mount transformer and therefore
does not provide any current regulation. However,
these devices offer a fixed internal current limit to

prevent damage to the internal powerFET.
A
time-limited pre-conditioning phase is provided to
condition deeply discharged cells. Once the battery
reaches the charge voltage, the high accuracy
voltage regulation loop takes over and completes the
charge cycle. Charge is terminated based on
minimum current. An internal charge timer provides a
backup safety for charge termination.

•
Charge-in-Progress, Charge Completion, and
Fault Conditions
Other standard features include an automatic sleep
mode activated when VCC falls below the battery
voltage and a recharge feature activated when the
battery voltage falls below the VRCH threshold.
Optional Temperature Monitoring Before and
During Charge
Small, 8-Pin Power-Pad MSOP Package
In addition to the standard features, the core product
provides two additional enhancements: temperature
monitoring and status display. The temperature-
sense circuit continuously measures battery
temperature using an external thermistor and inhibits
charge until the battery temperature is within the
user-defined thresholds. The STAT pin indicates
three conditions of operation of the charger. These
conditions are charge-in-progress, charge complete,
and fault. This output can be used to drive an LED or
an interface to a microcontroller.

APPLICATION INFORMATION
Figure 5. Low Dropout Single-Cell Li-Ion/Li-Pol Charger
FUNCTIONAL DESCRIPTION
The bq2420x supports a precision Li-Ion or Li-Pol charging system suitable for single-cells with either coke or
graphite anodes. Figure 5 shows an application schematic and Figure 6 shows the typical charge profile.
TEMPERATURE QUALIFICATION (bq24200 and bq24202 only)
The bq24200 and bq24201 continuously monitors battery temperature by measuring the voltage between the TS
and VSS pins. A negative- or a positive-temperature coefficient thermistor (NTC, PTC) and an external voltage
divider typically develop this voltage (see Figure 5). The bq24200 and bq24201 compare this voltage against the
internal V(TS1) and V(TS2) thresholds to determine if charging is allowed (see Figure 7). The temperature sensing
circuit is immune to any fluctuation in Vcc since both the external voltage divider and the internal thresholds are
referenced to Vcc.
Once a temperature outside the V(TS1) and V(TS2) thresholds is detected the bq24200 and bq24201 immediately
suspend the charge. The bq24200 and bq24201 suspend the charge by turning off the power FET and holding
the timer value (i.e., timers are NOT reset). Charge is resumed when the temperature returns to the normal
range.

Where RTC is the cold temperature resistance and RTH is the hot temperature resistance of thermistor, as

RT1 or RT2 can be omitted If only one temperature (hot or cold) setting is required. Applying a voltage between
the VTS1 and VTS2 thresholds to pin TS disables the temperature-sensing feature. Also applying a voltage
between (VCC – 0.3 V) and Vcc suspends the charge and places the IC in the low-power standby mode.
BATTERY PRE-CONDITIONING
Figure 7 shows the operational flow chart for the bq2420x.
Upon power-up, if the battery voltage is below the V(LOWV) threshold, the bq2420x applies a pre-charge current,
I(PRECHG), to the battery. This feature revives deeply discharged cells. The bq2420x activates a safety timer,
t(PRECHG), during the conditioning phase. If V(LOWV) threshold is not reached within the timer period, the bq2420x
turns off the charger and enunciates FAULT on the STAT pin. In the case of a FAULT condition, the bq2420x
reduces the current to I(DETECT). I(DETECT) is used to detect a battery replacement condition. Fault condition is
cleared by POR or battery replacement.
BATTERY CHARGE CURRENT
Following a successful pre-conditioning, the bq2420x relies on an external current-limited supply to limit the
charge current to the cell. The bq2420x continues this phase until the battery reaches the voltage regulation
phase.
During this phase (and all other phases of operation) in order to protect the integrated powerFET, the internal
short circuit and thermal protection circuits are active.
BATTERY VOLTAGE REGULATION
The voltage regulation feedback is through the BAT pin. This input is tied directly to the positive side of the
battery pack. The bq2420x monitors the battery-pack voltage between the BAT and VSS pins. The bq2420x is
offered in two fixed-voltage versions: 4.1 V and 4.2 V.
As a safety backup, the bq2420x also monitors the charge time in the voltage regulation mode. If taper current is
not detected within this time period, t(CHG), the bq2420x turns off the charger and enunciates FAULT on the STAT
pin. Fault condition is cleared by POR or battery replacement. Note that the safety timer is reset if the bq2420x is
forced out of the voltage regulation mode.
CHARGE TERMINATION AND RECHARGE
The bq2420x monitors the charging current during the voltage regulation phase. Once the taper threshold,
I(TAPER), is detected the bq2420x initiates the taper timer, t(TAPER). Charge is terminated after the timer expires.
The bq2420x resets the taper timer in the event that the charge current returns above the taper threshold,
I(TAPER)
.
In addition to the taper current detection, the bq2420x terminates charge in the event that the charge current falls
below the I(TERM) threshold. This feature allows for quick recognition of a battery removal condition.

SLUS501C–OCTOBER 2001–REVISED MARCH 2008
After a charge termination, the bq2420x restarts the charge once the voltage on the BAT pin falls below the
V(RCH) threshold. This feature keeps the battery at full capacity at all times.
SLEEP MODE
The bq2420x enters the low-power sleep mode if the Vcc is removed from the circuit (i.e., the Vcc and IN pins
are floating). For applications where these pins are not floating, placing a low-power 10 Ω (1/16 W) between the
IN and VCC pins ensures the V(SLP) conditions are met (see Figure 9).This feature prevents draining the battery
during the absence of VCC
.
Figure 9. Sleep Mode
CHARGE ENABLE PIN
The CE pin on bq24202, bq24203, bq24204 and bq24205 can be used to enable or suspend the charge. Charge
is enabled if the voltage VIL(CE) is applied to the pin. Applying the VIH(CE) suspends the charge. During a charge
suspend mode, the internal powerFET is turned off and all timers are reset.

The STAT pin on the bq2420x, indicates various conditions of operation. These conditions are summarized in

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
Important Information and Disclaimer:The information provided on this page represents TI's knowledge and belief as of the date that it is provided. TI bases its knowledge and belief on information
provided by third parties, and makes no representation or warranty as to the accuracy of such information. Efforts are underway to better integrate information from third parties. TI has taken and
continues to take reasonable steps to provide representative and accurate information but may not have conducted destructive testing or chemical analysis on incoming materials and chemicals.
TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for release.
In no event shall TI's liability arising out of such information exceed the total purchase price of the TI part(s) at issue in this document sold by TI to Customer on an annual basis.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
