ISL9212A - Charging System Safety Circuit
ISL9212A Charging System Safety Circuit The ISL9212A 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.
In addition to the above protected parameters, the IC also monitors its own internal tempe
