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.
