S-82A2B Datasheet Battery Protection

Manufacturer: ABLIC

Overview: S-82A2A/B/C Series www.ablic.com © ABLIC Inc., 2021-2023 BATTERY PROTECTION IC FOR 2-SERIAL-CELL PACK Rev.2.3_00 This IC is a protection IC for lithium-ion / lithium polymer rechargeable batteries, which includes high-accuracy voltage detection circuits and delay circuits. It is suitable for protecting 2-serial-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent. Use of an external overcurrent detection resistor enables this IC to provide high-accuracy overcurrent protection with less impact from temperature changes. The S-82A2A/C Series has an input pin for charge-discharge control signal (CTL pin), allowing for charge-discharge control with an external signal. The S-82A2B Series has an input pin for power-saving signal (PS pin), allowing for reduction of current consumption by using an external signal to start the power-saving function.

This datasheet includes multiple variants, all published together in a single manufacturer document.
