AP9234L
HIGH ACCURACY SINGLE CHIP SOLUTION FOR 1-CELL Li+ BATTERY PACK
Description
The AP9234L family is a single-chip protection solution specially
designed for 1-cell Li⁺ rechargeable battery pack application.
Pin Assignments
(Top View)
The AP9234L includes a 1-cell high accuracy Li⁺ battery protection
chip and dual N-CH, ultra low RSS(ON) MOSFET with common drain.
The AP9234L provides rich battery protection features and can turn-
off the N-Channel MOSFET by detecting overcharge voltage/current,
overdischarge voltage/current, or load short circuit. AP9234 has built-
in fixed delay time to save external components.
The AP9234L integrates highly accurate detection circuits and can
compensate according to internal MOSFET RSS(ON) performance to
ensure extremely high charge/discharge current accuracy under both
room and full temperature.
AP9234L is available in U-DFN2535-6 package.
