Diodes Incorporated AP9101C Single Chip Solution

Diodes Inc. AP9101C Single Chip Solution for 1-Cell Li+ Battery Pack is a protection IC developed for lithium-ion/lithium polymer rechargeable batteries. When the AP9101C detects overcharge, it turns off the external MOSFET switch to protect batteries. The AP9101C has a high-accuracy voltage detection circuit and an overcharge 3.5-4.5V detection voltage. The overcharge protection mode can be selectable from available/unavailable. The AP9101C also has a built-in fixed time circuit. The AP9101C is available in standard SOT-25 and SOT- 26 packages.
