ABLIC S-82x Battery Protection Supervisory Circuits
ABLIC S-82x Battery Protection Supervisory Circuits are protection ICs for lithium-ion and lithium polymer rechargeable batteries, including high-accuracy voltage detection circuits and delay circuits. Designed for 2-serial-cell packs, the S-82x ICs protect against overcharge, over-discharge, and overcurrent. These components provide high-accuracy overcurrent protection with less impact from temperature changes.
The S-82A2A/C series features an input pin for charge-discharge control signal (CTL pin), allowing for charge-discharge control with an external signal.
S-82A2B and S-82B2B have an input pin for the power-saving signal (PS pin). The PS pin reduces current consumption by using an external signal to start the power-saving function.
