ABLIC S-8204BAX-TCT1U

The S-8204B Series includes high-accuracy voltage detection circuits and delay circuits, in single use, makes it possible for users to monitor the status of 3-series or 4-series cell lithium-ion rechargeable battery. By switching the voltage level which is applied to the SEL pin, users are able to use the S-8204B Series either for 3-series or 4-series cell pack. By cascade connection using the S-8204B Series, it is also possible to protect 6-series or more cells' lithium-ion rechargeable battery pack.
