AP9214L
SINGLE CHIP SOLUTION FOR 1-CELL Li+ BATTERY PACK
Description
The AP9214L is a single chip protection solution specially designed
for 1-cell Li+ rechargeable battery pack application.
The AP9214L includes a 1-cell Lion battery protection chip and dual
N-CH, ultra low RSS(ON) MOSFET with common drain.
The AP9214L provides rich battery protection features and can turn-
off the N-CH MOSFET by detecting overcharge voltage/current, over
discharge voltage/current, or load short circuit. The AP9214L has
built-in fixed delay time to save external components.
