Part Number:TPS40303
What should happen to the TPS40303 when pin 2 is above the absolute maximum of 7V.
We are seeing low impedance between VDD (pin 1) and EN/SS (pin 2) due to surface corrosion caused by water. In many instances with 14VDC on VDD, the EN/SS pin is measuring 12.5VDC, whereas known good boards measure 5.5VDC.
If I remove the corrosion the TPS40303 works as intended.
Thanks,
Adam
