The ISL9212 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 t...
