Overview

DATASHEET ISL9209 Charging System Safety Circuit The ISL9209 is an integrated circuit (IC) optimized to provide a redundant safety protection to a Li-ion battery 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 temperature exceeds 140°C.
Together with the battery charger IC and the protection module in a battery pack, the charging system using ...
