BATTERY PROTECTION IC
FOR 3-SERIES OR 4-SERIES CELL PACK
S-8204A Series
Seiko Instruments Inc.
1
The S-8204A Series includes a voltage detection circuit with
high accuracy and a delay circuit, 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
this IC either for 3-series or 4-series cell pack.
By cascade connection using this IC, it is also possible to
protect 5-series or more cells
*1 rechargeable lithium-ion
battery pack.
*1. Refer to the usage guideline for connection examples of
protection circuit with 5-series cell.
