BQ76930: BQ78350-R1+BQ76930组合

Part Number: BQ76930
Other Parts Discussed in Thread: BQ78350-R1,

你好 ,BQ78350-R1+BQ76930组合的电路,想请教一下误 解除过充保护问题

BQstdio中设置COV Threshold 3.55V, Delay 2S Recovery3.3V

触发过充保护后MOS关断,并进行放电一段时间,再充电后达到3.55V COV保护值后切断MOS几秒又打开再切断,打开和切断的过程中没有触发到Recovery3.3V(磷酸铁锂电芯)。想请教一下可能是什么原因?我用示波器抓了BQ76930芯片的2引脚充电驱动电压,也是在11V和0V来回切换
