AP9101C

SINGLE CHIP SOLUTION FOR 1-CELL Li+ BATTERY PACK

Description

The AP9101C is a protection IC developed for lithium-ion/lithium

polymer rechargeable battery with a high-precision voltage, detection

circuit.

The AP9101C provides a function to protect batteries by detecting

overcharge voltage, overdischarge voltage, overcharge current,

overdischarge current and other abnormalities and turning off the

external MOSFET switch.

The AP9101C also has a built-in fixed time circuit (external capacitors

are unnecessary); the protection circuitry can be comprised with fewer

external components.

The AP9101C is available in standard packages of SOT25 and

SOT26.
