SP32106 Overvoltage and Overcurrent Protection IC and Li+Charger Front-End Protection IC The SP32106 devices are highly integrated circuits designed to provide protection to electronic system from failures of the charging circuit. The IC continuously monitors the input voltage, the input current. In case of an input overvoltage condition, the IC immediately removes power from the charging circuit by turning off an internal switch. In the case of an overcurrent condition, if the overcurrent persists, switches the pass element OFF after a blanking period. Additionally, the IC also monitors its own die temperature and switches off if it becomes too hot. The input overcurrent threshold is user programmable. The IC can be controlled by a processor and also provides status information about fault conditions to the host. 1 Features • Provides Protection for Three Variables: – Input Overvoltage Protection, With Rapid Response in < 100 ns – User-Programmable Overcurrent With Current Limiting – Thermal Shutdown • 32-V Maximum Input Voltage • Supports up to 1.5A Input Current • Robust Against False Triggering Due to Current Transients • Enable Input • Status Indication – Fault Condition • Available in Green DFN2×2-8L Packages 2 Applications • Bluetooth™ Devices • Electronic Cigarette Devices • Low-Power Handheld Devices • Smart Wearable Devices 技術銷售支持 李工 18938047300 |
