产品概述 返回TOP
The CXPR7157A/B/C provide complete Li+ charger protections against over-voltage, over-current, and battery overvoltage. The IC is designed to monitor input voltage, input current, and battery voltage. When any of the monitored parameters are over the threshold, the IC removes the power from the charging system by turning off an internal switch. All protections also have deglitch time against false triggering due to voltage spikes or current transients. The CXPR7157A/B/C also provide over-temperature protection, a FAULT output pin to indicate the fault conditions, and the EN pin to allow the system to disable the IC.
