BQ24133 沒外部電源時,STAT Pin輸出啟動

Other Parts Discussed in Thread: BQ24133

Hi TI:

无外部电源,电池供电至BQ24133的 AVCC Pin时

电池连续抽载Peak 10A,会因AVCC Pin的Bypass cap 1uF储能,造成AVCC Pin瞬间电压高于SRN Pin,导致BQ24133启动VREF。

因此我将AVCC Pin改成只接外部电源(12V),所以需要确认以下问题:

 

当没有外接电源(12V Adapter)时,AVCC Pin没有电源,但是PVCC/ACP/ACN/SW/SRP/SRN Pin有8.4V电压(2-Cell),是否对IC会有任何影响?

还请尽快帮忙回复,非常感谢
