Other Parts Discussed in Thread: TPS3838, TPS3837, TPS3836
HI,
My customer is facing that TPS3838L30 sometime doesn't perform correct reset out under certain condition.
it happened that very first time power cycle (12V ramp then ACC S/W ON).
It happened that power cycle again by ACC S/W ON-> OFF -> ON many times.
Please find attached file which shows OK case and NG case waveforms.
Also circuit and power tree.
Could you please suggest which is an problem point or possible cause?
Please suggest where I need to check around TPS3838L30.
Regards,
Kasuya
