Seiko Instruments Inc.

1

The S-8233C Series is a series of lithium-ion rechargeable battery

protection ICs incorporating high-accuracy voltage detection circuits and

delay circuits.

The S-8233C series includes the function to measure the status of

battery pack.

It is suitable for a 3-serial-cell lithium-ion battery pack.
