Other Parts Discussed in Thread: LM43602-Q1
Hello,
I am seeing a negative voltage at Cathode of LM74610-Q1 in reverse battery condition. Specifically, Anode is at -13.5V.
The negative voltage is at -0.45V caused by the reverse leakage current (ILKG) from Cathode to Anode of typically 60uA. This is all right for LM74610-Q1, but is a serious problem for LM43602-Q1, which is in the downstream. The negative voltage is out of the rating of LM43602-Q1 at -0.3V.
Do you have any good idea to avoid this situation?
Thanks.
Regards,
Oguri
