Seiko Instruments S-8225A
The S-8225A Series includes high-accuracy voltage detection circuits and delay circuits, and can monitor the status of 3-serial to 5-serial cell lithium-ion rechargeable battery in single use. By switching the voltage level which is applied to the SEL1 pin and SEL2 pin, users are able to use the S-8225A Series for 3-serial to 5-serial cell pack. By cascade connection using the S-8225A Series, it is also possible to protect 6-serial or more cells lithium-ion rechargeable battery pack.| Part No. | S-8225A |
