Dual Input Li-ion/Li-Polymer Battery

Features

Charger With Battery Removal Detection

• Complete Charger for Single-Cell Li-ion/Polymer Batteries

• Dual Input Power Sources for Cradle and USB

• Battery Removal Detection

The ISL9228 is a fully integrated low-cost single-cell Li-ion or

Li-polymer battery charger. The charger accepts two power

inputs, normally one from a USB (Universal Serial Bus) port

and the other from a desktop cradle. The ISL9228 is an ideal

charger for smart handheld devices that need to

• Integrated Pass Elements

• Fixed 380mA USB Charge Current

communicate with a personal computer via USB.

• Programmable Cradle Charge Current

The ISL9228 features 28V maximum voltages for both the

cradle and the USB inputs. Due to the 28V rated inputs, low-

cost, large output tolerance adapters can be used safely.

The 28V rating eliminates the over voltage protection circuit

required in a low input voltage charger.

• Charge Current Thermaguard™ for Thermal

Protection

• 28V Maximum Voltages for Cradle and USB Inputs

• 1% Constant Voltage Accuracy

When both inputs are powered, the cradle input is used to

charge the battery. The charge current is programmable for

the cradle input with a small resistor. The end-of-charge

current is also programmable by another external resistor.

The charger incorporates Thermaguard™ which protects the

IC against over temperature. If the die temperature rises

above a typical value of +125°C, a thermal foldback function

reduces the charge current automatically to prevent further

temperature rise. The charger has two indication pins. The

PPR (power present) pin outputs an open-drain logic LOW

when either the cradle or the USB input power is attached.

The CHG (charge) pin is also an open-drain output that

indicates a logic LOW when the charge current is above a

minimum current level. When the charge current is below the

preset minimum current, the CHG pin will turn to logic high to

indicate the end-of-charge condition.

• Adapter Presence and Charge Indications

• Less than 0.5µA Leakage Current off the Battery when No

Input Power Attached

• Programmable End-of-Charge Current

• Ambient Temperature Range: -40°C to +85°C

• No External Blocking Diode Required

• Pb-Free (RoHS Compliant)

Functional Pin Description

CRDL (Pin 1)

EN (Pin 5)

Cradle input. This pin is usually connected to a cradle power

input. The maximum input voltage is 28V. The charge

current from this pin is programmable with the ICDL pin up to

1A. When this pin is connected to a power source, no charge

current is drawn from the USB pin. A 1µF or larger value

ceramic capacitor is recommended for decoupling.

Enable logic input. Connect to LOW or leave floating to

enable the charger.

IMIN (Pin 6)

IMIN is the programmable input for the end-of-charge

current. IMIN is calculated by Equation 1:

USB input. This pin is usually connected to a USB port

power connector. Other sources that are also acceptable.

The charge current from the USB pin is fixed at typically

380mA. A 1µF or larger value ceramic capacitor is

recommended for decoupling. It is also recommended to

have a 1Ω resistor in series with the decoupling capacitor to

prevent an over-shoot voltage when a USB cable is plugged

in.

VF (Pin 7)

VF is an input pin for the battery ID resistor connection. This

pin has an internal 1000kΩ pull-up resistor. Thus a typical

20kΩ ID resistor will pull this pin to logic low state, indicating

a valid battery connection. If the battery is removed, the VF

pin will be pulled to a logic high state by the internal resistor,

the charger will be disabled as a result, regardless of the

status of the EN pin. The maximum ID resistor is 100kΩ.

PPR (Pin 3)

Power presence indication. An open-drain output pin which

turns ON when either the USB input voltage or the CRDL

input voltage is within the power good range (refer to the

Description section for definition of power good condition),

regardless if the charger is enabled or disabled. Otherwise

turns OFF. This pin provides a wake-up signal to a

microprocessor when either the cradle or the USB power is

connected.

GND (Pin 8)

System ground.

ICDL (Pin 9)

The ICDL pin has two functions. The first function is to

program the cradle charge current during the constant-

current mode. The voltage of this pin is 1.22V during the

constant-current mode of the cradle charger. The constant-

current mode current is programmed by Equation 2:

CHG (Pin 4)

Charge indication pin. An open-drain output which turns ON

when the charge current is above programmable threshold.

Otherwise turns OFF.

and the charger drops out the constant current regulation.

It is recommended that the charge current be programmed

in the range of 100mA to 1000mA.

Cradle Charge Current

The cradle charge current is programmed with the external

resistor connected between the ICDL pin and the GND pin.

the battery cell. A 1µF or larger value ceramic capacitor is

recommended for decoupling. The charger relies on the

When the battery voltage is below the minimum battery

voltage V

Description

operates in a trickle/preconditioning mode, where the charge

current is typically 18% of the programmed charge current

for the cradle input. If power comes from the USB input, the

trickle current is approximately 80mA.

The ISL9228 is designed for a single-cell Li-ion or Li-polymer

battery charging circuit that accepts both a USB port and a

desktop cradle as its power source. While the charge current

from the USB input source is fixed at 380mA, the charge

current from the cradle input is programmable between 0.1A

When an EOC condition (charge current falls below I

during constant voltage charge) is encountered, the CHG pin

current is programmable by connecting a resistor at the IMIN

pin. The end-of-charge threshold can be calculated with

same threshold applies to both the cradle and the USB inputs.

programmable by the resistor at the IMIN pin for both cradle

and USB inputs. Once the EOC condition is reached, the

status is latched and can be reset at one of the following

conditions:

Input Auto Selection

When both input sources are present, the charger selects

only one power source to charge the battery. When the

CRDL input is higher than the POR threshold, CRDL is

selected as the power source. Otherwise the USB input is

selected. If the CRDL input voltage is below the battery

voltage but the USB input voltage is higher than the battery

voltage, then the USB input is used to charge the battery.

The control circuit always breaks both internal power

devices before switching from one power source to the other

to avoid a cross conduction of both power MOSFETs.

1. The part is disabled and re-enabled

2. The selected input source has been removed and re-

applied

3. The BAT pin voltage falls below the recharge threshold

USB Charge Current

When the USB port is selected as the power source, the

charge current enabled by the logic input at the EN pin.

When the EN is driven to logic LOW, the charger is enabled.

Typically the P-channel MOSFET for the USB input has an

of 600mΩ at room temperature. With a 380mA

DS(ON)

charge current, the typical head room is 228mV. Thus, if the

input voltage drops to a level that the voltage difference

between the USB pin and the BAT pin is less than 228mV,

Thermal Foldback (Thermaguard™)

Trickle

The thermal foldback function reduces the charge current

when the internal temperature reaches the thermal foldback

threshold, which is typically +125°C. This protects the

charger from excessive thermal stress at high input voltages.

Due to the inductance of the power leads of the wall adapter

or USB source, the input capacitor type must be properly

selected to prevent high voltage transient during a hot-plug

event. A tantalum capacitors is a good choice for its high

ESR, providing damping to the voltage transient. Multi-layer

ceramic capacitors, however, have a very low ESR and

hence when chosen as input capacitors, a 1-Ω series

resistor must be used, as shown in the Typical Applications

Section, to provide adequate damping.

Figure 11 shows the typical charge profile including the

State Diagram

The state diagram for the charger functions is shown in

Figure 12. The diagram starts with the Power-Off state.

When at least one input voltage rises above the POR

threshold, the charge resets it self. If both input voltages are

in the power good range, the charger selects the CRDL input

as the power source. Then if the EN pin is at a logic HIGH

voltage, the charger stays in disabled state. If the EN pin

goes LOW, the fast charge starts. Any time the EN pin turns

HIGH, the charger returns to the disabled state. When the

EOC condition is reached, the CHG will turn to logic HIGH to

indicate a charge complete status but the charge will

continue. The EOC condition is then latched until one of the

three re-charge conditions is encountered, as shown in

Figure 11.

Power Presence Indication

When either the USB or the cradle input voltage is above the

POR threshold, the PPR pin internal open-drain MOSFET

turns on indicating the presence of input power.

Power-Good Conditions

Even if there is a power present, the charger will not deliver

any current to the output if the power-good conditions are

not met. The following two conditions together define the

power-good voltage range:

1. VCDRL or VUSB > VPOR

2. VCDRL or VUSB - VBAT > VOS

where VPOR is the power on reset threshold, VOS is the

offset voltage for the input and output voltage comparator. All

these thresholds have hysteresis, as given in the “Electrical

Specification” table on page 4. The charger will not charge

the battery if the input voltage does not meet the power-good

conditions.
