1 / 11 page 1 ® FN9241.0 ISL9200 Charging System Safety Circuit The ISL9200 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 the P-channel MOSFET when the die temperature exceeds 140°C. Together with the battery charger IC and the protection module in a battery pack, the charging system using the ISL9200 has triple-level protection and is two-fault tolerant. The IC is designed to turn on the internal PFET slowly to avoid inrush current at power-up but will turn off the PFET quickly when input overvoltage is detected, in order to remove the power before any damage occurs. The ISL9200 has a logic warning output to indicate the fault and an enable input to allow the system to remove the input power. Typical Application Circuit 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) Applications • Cell Phones • Digital Still Cameras • PDAs and Smart Phones • Portable Instruments • Desktop Chargers Related Literature • Technical Brief TB363 “Guidelines for Handling and Processing Moisture Sensitive Surface Mount Devices (SMDs)” • Technical Brief TB379 “Thermal Characterization of Packaged Semiconductor Devices” • Technical Brief TB389 “PCB Land Pattern Design and Surface Mount Guidelines for QFN Packages” Ordering Information PART # PART MARKING TEMP.
