Describes

This IC is a monitoring IC for automotive rechargeable batteries, which includes high-accuracy voltage detection circuits and delay circuits. Switching control for 3-serial to 6-serial cell is possible by inputting voltage to the SEL1 pin and the SEL2 pin.

By cascade connection, it is possible to protect 7-serial or more cells lithium-ion rechargeable battery pack. In addition, this IC can perform a self-test to confirm overcharge and overdischarge detection operations. 

Application

• Automotive rechargeable battery pack (EV, HEV, PHEV, etc.)
