I have 3 boards that shares same power input schematic from battery power. I use SRC0CS25D to control power up of board.
First two boards works great.
The third board works, but the 3 sample which i used for debug purpose, after a while they fail to power up.
In all case, the PB voltage (pin 6) is below 2V (in same cases below 1V) and no VREF or below 1.5 VREF voltage on pin 3.
I tried to remove capacitors on those pin and replace, with no results.
In one board i tried to change IC, with no results. Before try on other board, I want to check if some errors. Attached the relative portion of schematic.
Can anyone help me?
Thanks
