ABLIC S-82P1A and S-82P1B Battery Protection ICs for lithium-ion/lithium polymer rechargeable batteries that include high-accuracy voltage detection circuits and delay circuits. The ICs are suitable for protecting 1-cell lithium-ion/lithium polymer rechargeable battery packs from overcharge, over-discharge, and overcurrent. These ICs realize high-accuracy overcurrent protection with less effect from temperature change by using an external overcurrent detection resistor. The S-82P1A and S-82P1B ICs feature discharge overcurrent control function and detection delay times that are generated only by an internal circuit. These S-82P1A and S-82P1B ICs operate from -40°C to 85°C temperature range and -55°C to 125°C storage temperature range. Typical applications include a lithium-ion rechargeable battery pack and a lithium polymer rechargeable battery pack.
