BATTERY MONITORING IC FOR 3-SERIAL TO 5-SERIAL CELL PACK
Rev.1.4_00
The S-8255A Series is a monitoring IC for 3-serial to 5-serial cell lithium-ion rechargeable batteries, which includes high-accuracy voltage detection circuits and delay circuits. The S-8255A Series can monitor the status of 3-serial to 5-serial cell lithium-ion rechargeable battery packs. Cascade connection using the S-8255A Series realizes monitoring 6-serial or more cells lithium-ion rechargeable battery packs. Connecting an NTC, it allows for the temperature detection at four different points: high temperature detection during charging, low temperature detection during charging, high temperature detection during discharging, and low temperature detection during discharging.
