ISL9211B Charging System Safety Circuit The ISL9211B is an integrated circuit (IC) optimized to provide a redundant safety protection to a Li-ion battery charging system.

The IC monitors input voltage, battery voltage, and charge current.

When any of these parameters exceeds its limit, the IC turns off an internal N-channel MOSFET to remove power from the charging system to the battery.

The IC also monitors its own internal temperature and turns off the N-channel MOSFET when the temperature exce
