Protection device for lithium-ion / lithium polymer rechargeable batteries

Mouser is now stocking the Diodes Inc. AP9101C, a single-chip solution for 1-cell Li+ battery packs. The protection IC was developed for lithium-ion / lithium polymer rechargeable batteries with a high-precision voltage, detection circuit. The AP9101C protects batteries by turning off the external MOSFET switch when detecting over-charge voltage, over-discharge voltage, over-charge current, over-discharge current and other abnormalities. 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 SOT-25 and SOT- 26 packages.
