Part Number:BQ76952Other Parts Discussed in Thread: BQSTUDIO
您好,BQ76952做的16串管理系统,LD引脚电压正常情况应该是与BAT+一致大约(50V),实际上万用表量到的电压是15V,bqstudio采集的电压显示是20V,请问如何解决呢?

您好,请参考下面的内容
From what I can see from reading the datasheet and technical reference manual (TRM). This voltage is from a current-source in the LD pin activated after OCD/SCD protections are triggered. If a load with low impedance is connected, the pin will generally be held low below the 4-V line. If a load is disconnected the LD pin will tend to pull high, and recovering from the protections. See Section 5.2.18 Load Detect Functionality of the TRM and Section 11.6 Load Detect Functionality of the datasheet.
