ISL9212B Charging System Safety Circuit

ISL9212B Charging System Safety Circuit The ISL9212B 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.

ISL9212B Features

* Fully Integrated Protection Circuit for Three Protection Variables - User Programmable Overcurrent Protection Threshold - Input Overvoltage Protection in Less Than 1µs - Battery Overvoltage Protection

* High Immunity of False Triggering Under Transients

* High Accuracy Prot
