APM8601
DUAL CHANNEL SINGLE CELL LINEAR LITHIUM BATTERY
CHARGER WITH 28V OVP and PROGRAMMABLE CHARGE
TIMER
Description
Pin Assignments
The APM8601 is a dual input channel linear Li-Ion charger for
portable equipment that is optimized for small form-factor
applications.
The charge algorithm in the APM8601 covers all the charge
requirements for a single Li-Ion battery cell. Included is
pre-charging for deeply discharged cells, constant current /
constant voltage fast charging and a top-off feature to bring
the cell safely to a full-charge level.
The battery is constantly monitored for overvoltage, charge
time and cell temperature to ensure safe charging. A fault is
triggered once the charge time exceeds a value that is
programmable using a single capacitor and the temperature
measurement is achieved through a thermistor positioned
close to the battery cell.
The APM8601 automatically selects the USB or DC input,
depending on which is valid (DC has priority if both are valid).
The charging current from the USB input is set to 100mA or
500mA based on the logic level of the USEL input.
The APM8601 is packaged in U-DFN3030-14 package with a
thermal pad.
