The AP9101C is a protection IC designed with 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.
