ISL9200 Overview
ISL9200 Charging System Safety Circuit The ISL9200 is an integrated circuit (IC) optimized to provide a Li-ion battery redundant safety protection from failures of a charging system. The IC monitors the input voltage, the battery voltage, and the charge current. When any of the three parameters exceeds its limit, the IC turns off an internal P-channel MOSFET to remove the power from the charging system.
