Overview

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.

Key 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 Protection Thresholds.
  • Warning Output to Indicate the Occurrence of Faults.
  • Enable Input.
  • Thermal Enhanced DFN Package.
  • Pb-Free Plus Anneal Available (RoHS Compliant).
