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 MOS.
• 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)
Applications
• Cell Phones
• Digital Still Cameras
• PDAs and Smart Phones
• Portable Instruments
• Desktop Chargers
