CXPR7156A CXPR7156B提供完整的锂+充电器保护，防止过电压、过电流和电池过电压。该集成电路设计用于监测输入电压、输入电流和电池电压。当任何监测参数超过阈值时，IC通过关闭内部开关来切断充电系统的电源。所有保护装置也有防电压尖峰或电流瞬变引起误触发的脱胶时间。CXPR7156A/B还提供过温保护、指示故障状态的故障输出引脚和允许系统禁用IC的EN引脚。

产品概述 返回TOP
The CXPR7156A/B provide completed 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 CXPR7156A/B 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.
