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.
In addition to the above protected parameters, the IC also monitors its own internal temperature and turns off the P-channel
MOSFET when the die temperature exceeds 140°C.
Together with the battery charger IC and the protection module in a battery pack, the charging system using the ISL9200 ...
