bq24314A Overvoltage and Overcurrent Protection IC and
Li+ Charger Front-End Protection IC Features 3 DescriptionThe bq24314A deviceisa highly integrated circuit Provides Protection for Three Variables: (IC) designedto provide protectionto Li-ion batteries– Input Overvoltage, With Rapid Responsein from failures of the charging circuit. The device<1µs continuously monitors the input voltage, the input User-Programmable Overcurrent With Current current, and the battery voltage.In caseof an input
overvoltage condition, the device immediatelyLimiting
removes power from the charging circuit by turning– Battery Overvoltage off an internal switch.In the caseof an overcurrent• Maximum Input Voltageof30V condition,it limits the system currentat the threshold Supportsupto 1.5-A Input Current value, andif the overcurrent persists, switches the
pass element OFF after a blanking period.• Robust Against False Triggering Dueto Current Additionally, the device also monitors its own dieTransients temperature and switchesoffifit exceeds 140°C. The• Thermal Shutdown input overcurrent thresholdis user-programmable. Enable Input The device canbe controlledbya processor and also• Status Indication– Fault Condition provides status information about fault conditionsto Availablein Space-Saving Small8 Lead2×2 the host.
