AP9101C
SINGLE CHIP SOLUTION FOR 1-CELL Li+ BATTERY PACK
Description
Features
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.
