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. Applications  Lithium-Ion Battery Packs  Lithium Polymer Battery Packs Features  Low Current Consumption (+25°C)  Operation Mode: 3.
