USB power supply input.
Battery charging and sensing.
Adapter input.
Ground connection.
Resistor divider to set USB voltage regulation for charge reduction mode.
Leave this pin open for default 4.5V USB regulation point. Tie to USB pin to
disable this function.
Enable pin. Logic high enables the IC.
Adapter present indicator. This pin is open drain until ADP pin reaches
threshold.
Connect to 10k
Ω
NTC thermistor.
Status report to microcontroller via serial interface, open-drain.
Battery charge status indicator pin to drive an LED: active low, open-drain.
Battery charge status indicator pin to drive an LED: active low, open-drain.
Timing capacitor to adjust internal watchdog timer. Set maximum charge time
for adapter powered trickle, CC, and CV charge modes. The watchdog timer
only sets the timers for adapter battery charging; there is no timeout for the
battery charging from the USB input. If timing function is not needed, termi-
nate this pin to ground.
When USB is present, use this pin to toggle between 100mA and 500mA limit.
Connect resistor here to set charge current for low-current USB port.
Connect resistor here to set charge current for high-current USB port.
Use resistor at this pin to set adapter charging current.
Exposed paddle (bottom); connect to GND directly beneath package.
