MCP73213

Dual-Cell Li-Ion / Li-Polymer Battery Charge Management

Controller with Input Overvoltage Protection

Features

Description

• Complete Linear Charge Management Controller:

- Integrated Input Overvoltage Protection

- Integrated Pass Transistor

The MCP73213 is a highly integrated Li-Ion battery

charge management controller for use in space-limited

and cost-sensitive applications. The MCP73213

provides specific charge algorithms for dual-cell Li-Ion

/ Li-Polymer batteries to achieve optimal capacity and

safety in the shortest charging time possible. Along

with its small physical size, the low number of external

components makes the MCP73213 ideally suitable for

portable applications. The absolute maximum voltage,

up to 18V, allows the use of MCP73213 in harsh

environments, such as low cost wall wart or voltage

spikes from plug/unplug.

- Integrated Current Sense

- Integrated Reverse Discharge Protection

• Constant Current / Constant Voltage Operation

with Thermal Regulation

• 4.15V Undervoltage Lockout (UVLO)

• 13V Input Overvoltage Protection

• High Accuracy Preset Voltage Regulation

Through Full Temperature Range (-5°C to +55°C):

The MCP73213 employs a constant current / constant

voltage charge algorithm. The various charging voltage

regulations provide design engineers flexibility to use in

different applications. The fast charge, constant current

value is set with one external resistor from 130 mA to

1100 mA. The MCP73213 limits the charge current

based on die temperature during high power or high

ambient conditions. This thermal regulation optimizes

the charge cycle time while maintaining device

reliability.

BATTERY CHARGE CONTROL

5.0

5.1

DETAILED DESCRIPTION

Undervoltage Lockout (UVLO)

OUTPUT (V

)

BAT

The battery charge control output is the drain terminal

of an internal P-channel MOSFET. The MCP73213

provides constant current and voltage regulation to the

battery pack by controlling this MOSFET in the linear

region. The battery charge control output should be

connected to the positive terminal of the battery pack.

An internal undervoltage lockout (UVLO) circuit

monitors the input voltage and keeps the charger in

shutdown mode until the input supply rises above the

UVLO threshold. In the event a battery is present when

the input power is applied, the input supply must rise

approximately 150 mV above the battery voltage

before the MCP73213 device become operational.

5.3.3

BATTERY DETECTION

The MCP73213 detects the battery presence with

charging of the output capacitor. The charge flow will

initiate when the voltage on V_BATis pulled below the

The UVLO circuit places the device in shutdown mode

if the input supply falls to approximately 150 mV above

the battery voltage.The UVLO circuit is always active.

At any time, the input supply is below the UVLO

threshold or approximately 150 mV of the voltage at the

V_BATpin, the MCP73213 device is placed in a

shutdown mode.

V_RECHARGEthreshold.

Refer

to

Section 1.0

“Electrical Characteristics” for V_RECHARGEvalues.

The value will be the same for non-rechargeable

device.

When V_BAT> V_REG+ Hysteresis, the charge will be

suspended or not start, depends on the condition to

prevent over charge that may occur.

5.2

Overvoltage Protection (OVP)

An internal overvoltage protection (OVP) circuit

monitors the input voltage and keeps the charger in

shutdown mode when the input supply rises above the

typical 13V, OVP threshold. The hysteresis of OVP is

approximately 150 mV for the MCP73213 device.

5.4

Preconditioning

If the voltage at the V_BATpin is less than the

preconditioning threshold, the MCP73213 device

enters a preconditioning mode. The preconditioning

threshold is factory set. Refer to Section 1.0

“Electrical Characteristics” for preconditioning

threshold options.

The MCP73213 device is operational between UVLO

and OVP threshold. The OVP circuit is also recognized

as overvoltage lock out (OVLO).

In this mode, the MCP73213 device supplies 10% of

the fast charge current (established with the value of

the resistor connected to the PROG pin) to the battery.

5.3

Charge Qualification

When the input power is applied, the input supply must

rise 150 mV above the battery voltage before the

MCP73213 becomes operational.

When the voltage at the V_BATpin rises above the

preconditioning threshold, the MCP73213 device

enters the constant current (fast charge) mode.

The automatic power down circuit places the device in

a shutdown mode if the input supply falls to within

+50 mV of the battery voltage.

Note:

5.4.1

The MCP73213 device also offers options

with no preconditioning.

The automatic circuit is always active. At any time the

input supply is within +50 mV of the voltage at the

V_BATpin, the MCP73213 is placed in a shutdown

mode.

TIMER EXPIRED DURING

PRECONDITIONING MODE

If the internal timer expires before the voltage threshold

is reached for fast charge mode, a timer fault is

indicated and the charge cycle terminates. The

MCP73213 device remains in this condition until the

battery is removed or input power is cycled. If the

battery is removed, the MCP73213 device enters the

Stand-by mode where it remains until a battery is

reinserted.

For a charge cycle to begin, the automatic power

down conditions must be met and the charge enable

input must be above the input high threshold.

5.3.1

BATTERY MANAGEMENT INPUT

DD

The V_DDinput is the input supply to the MCP73213.

The MCP73213 automatically enters a Power-down

mode if the voltage on the V_DDinput falls to within

+50 mV of the battery voltage. This feature prevents

draining the battery pack when the V_DDsupply is not

present.

Note:

The typical preconditioning timer for

MCP73213 is 32 minutes. The MCP73213

also offers options with no preconditioning

timer.

The MCP73213 device continuously monitors the

voltage at the V_BATpin in the charge complete mode. If

the voltage drops below the recharge threshold,

another charge cycle begins and current is once again

supplied to the battery or load. The recharge threshold

is factory set. Refer to Section 1.0 “Electrical

Characteristics” for recharge threshold options.

Note:

The MCP73213 also offers options with no

automatic recharge.

For the MCP73213 device with no recharge option, the

MCP73213 will go into standby mode when termination

condition is met. The charge will not restart until

following condition has met:

• Battery is removed from system and insert again

• V_DDis removed and plug in again

•

5.12 Battery Short Protection

Once a single-cell Li-Ion battery is detected, an internal

battery short protection (BSP) circuit starts monitoring

the battery voltage. When V_BATfalls below a typical

1.7V battery short protection threshold voltage, the

charging behavior is postponed. 25 mA (typical)

detection current is supplied for recovering from battery

short condition.

FIGURE 5-1:

Thermal Regulation.

5.10 Thermal Shutdown

The MCP73213 suspends charge if the die

temperature exceeds +150°C. Charging will resume

when the die temperature has cooled by approximately

10°C. The thermal shutdown is a secondary safety

feature in the event that there is a failure within the

thermal regulation circuitry.

Preconditioning mode resumes when V_BATraises

above battery short protection threshold. The battery

voltage must rise approximately 150 mV above the

battery short protection voltage before the MCP73213

device become operational.

5.11 Status Indicator

The charge status outputs are open-drain outputs with

two different states: Low (L), and High Impedance

(Hi-Z). The charge status outputs can be used to

illuminate LEDs. Optionally, the charge status outputs

can be used as an interface to a host microcontroller.

Table 5-2 summarize the state of the status outputs

during a charge cycle.

Power dissipation with a 9V, ±10% input voltage

source, 500 mA ±10% and preconditioning threshold

voltage at 6V is:

6.1

Application Circuit Design

Due to the low efficiency of linear charging, the most

important factors are thermal design and cost, which

are a direct function of the input voltage, output current

and thermal impedance between the battery charger

and the ambient cooling air. The worst-case situation is

when the device has transitioned from the

Preconditioning mode to the Constant-current mode. In

this situation, the battery charger has to dissipate the

maximum power. A trade-off must be made between

the charge current, cost and thermal requirements of

the charger.

EQUATION 6-2:

PowerDissipation = (9.9V – 6.0V) × 550mA = 2.15W

This power dissipation with the battery charger in the

DFN-10 package will result approximately 92°C above

room temperature.

6.1.1.3

External Capacitors

6.1.1

COMPONENT SELECTION

The MCP73213 is stable with or without a battery load.

In order to maintain good AC stability in the Constant-

voltage mode, a minimum capacitance of 1 µF is

recommended to bypass the V_BATpin to V_SS. This

capacitance provides compensation when there is no

battery load. In addition, the battery and

interconnections appear inductive at high frequencies.

These elements are in the control feedback loop during

Constant-voltage mode. Therefore, the bypass

capacitance may be necessary to compensate for the

inductive nature of the battery pack.

Selection of the external components in Figure 6-1 is

crucial to the integrity and reliability of the charging

system. The following discussion is intended as a guide

for the component selection process.

6.1.1.1

Charge Current

The preferred fast charge current for Li-Ion / Li-Poly

cells is below the 1C rate, with an absolute maximum

current at the 2C rate. The recommended fast charge

current should be obtained from battery

manufacturer. For example, a 500 mAh battery pack

with 0.7C preferred fast charge current has a charge

current of 350 mA. Charging at this rate provides the

shortest charge cycle times without degradation to the

battery pack performance or life.

A minimum of 16V rated 1 µF, is recommended to apply

for output capacitor and a minimum of 25V rated 1 µF,

is recommended to apply for input capacitor for typical

applications.

Thermal Considerations

The worst-case power dissipation in the battery

charger occurs when the input voltage is at the

maximum and the device has transitioned from the

Preconditioning mode to the Constant-current mode. In

this case, the power dissipation is:

Virtually any good quality output filter capacitor can be

used, independent of the capacitor’s minimum

Effective Series Resistance (ESR) value. The actual

value of the capacitor (and its associated ESR)

depends on the output load current. A 1 µF ceramic,

tantalum or aluminum electrolytic capacitor at the

output is usually sufficient to ensure stability.

PCB Layout Issues

For optimum voltage regulation, place the battery pack

as close as possible to the device’s V_BATand V_SSpins,

recommended to minimize voltage drops along the

high current-carrying PCB traces.

If the PCB layout is used as a heatsink, adding many

vias in the heatsink pad can help conduct more heat to

the backplane of the PCB, thus reducing the maximum

junction temperature. Figure 6-4 and Figure 6-5 depict

a typical layout with PCB heatsinking.

NOTES:

DS22190A-page 32

Note the following details of the code protection feature on Microchip devices:

•

Microchip products meet the specification contained in their particular Microchip Data Sheet.

•

Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

•

There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

•

Microchip is willing to work with the customer who is concerned about the integrity of their code.

Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Information contained in this publication regarding device

applications and the like is provided only for your convenience

and may be superseded by updates. It is your responsibility to

ensure that your application meets with your specifications.

INCLUDING BUT NOT LIMITED TO ITS CONDITION,

QUALITY, PERFORMANCE, MERCHANTABILITY OR

arising from this information and its use. Use of Microchip

devices in life support and/or safety applications is entirely at

the buyer’s risk, and the buyer agrees to defend, indemnify and

hold harmless Microchip from any and all damages, claims,

suits, or expenses resulting from such use. No licenses are

conveyed, implicitly or otherwise, under any Microchip

intellectual property rights.
