ABLIC Launches the S-82Y1B Series of 1-cell Battery Protection ICs with the Upgraded World�s Highest (*1) Charge-discharge Overcurrent Detection Voltage Accuracy of �0.5mV (*2)

Combine Industry�s Top Class Fast Charging with Even Better Safety

TOKYO--(BUSINESS WIRE)--ABLIC (President: Nobumasa Ishiai, head office: Minato-ku, Tokyo hereinafter �ABLIC�), a group company of MinebeaMitsumi Inc., today launched the S-82Y1B Series of 1-cell battery protection ICs with the world�s highest (*1) charge-discharge overcurrent detection voltage accuracy of �0.5mV (*2).

The new S-82Y1B Series of 1-cell lithium-ion battery protection ICs launched today is the upgraded version of our S-82P1 Series. The new ICs (1) raise the charge-discharge overcurrent detection voltage accuracy from �0.75mV of the S-82P1 Series to the world�s highest accuracy of �0.5mV and suppress overcurrent detection variations while lowering current detection resistance, (2) provide three-stage discharge overcurrent protection, each stage of which ensures the industry�s top class accuracy capable of reducing abnormal current to an even safer level, and (3) also boast the industry�s top class overcharge detection voltage accuracy of �15mV.

These features enable the ICs to suppress heat generation in the protection circuit board even as the charge current increases. Their capability to reduce abnormal current to a safer level and their high accuracy overcharge detection significantly contribute to greater product safety. A full lineup allows us to provide customers with the products they are looking for.

(*1) Based on our research as of October 2022

(*2) 33% lower than our previous products
