5 说明(续)  
此器件可通过集成的独立 CHG DSG 低侧 NMOS FET 驱动器实现电池组保护,这些驱动器可通过两个控制引  
脚禁用。这些控制引脚还能够以简单经济的方式为更多节串联电池(6 节及以上)提供电池保护解决方案。为此,  
只需将上级器件的 CHG DSG 输出级联到下级器件控制引脚。为实现更大的灵活性,放电过流保护延迟可以通  
过从 OCDP 引脚连接至 VSS 的电阻器进行编程。  
BQ77915 保护器通过可实现高达 50mA 电池平衡电流的集成式 FET,实现了智能被动电池平衡算法。对于更高的  
电池平衡电流要求,可通过连接外部 FET 的方式实现。旨在用于电池组运输和贮存之目的的休眠模式可支持超低  
功耗运行。  
BQ77915 保护器可用于无需主机监控的电池组。

(1) These thresholds are targets, based on temperature, but they are dependent on external components that could vary based on  
customer selection. The circuit is based on a 103AT NTC thermistor connected to TS and VSS, and a 10-kΩ resistor connected to  
VTB and TS. Actual thresholds must be determined in mV; refers to the overtemperature and undertemperature mV threshold in the  
Electrical Characteristics table.
