UCD3138: UCD3138RJAR DPWM OUTPUT HIGH DURING V33D START-UP

Part Number: UCD3138

Hi Sir:

We are using UCD3138RJAR to replace old UCD3138RHAR, while we found this issue during test; at high temperature, like 70'c, we saw DPWM output high following V33D during start-up, waveform is attached;

CH1:V33D, CH2:DPWM0B

after that, the UCD3138RJAR could work normally; when we use old UCD3138RHAR, we didn't see this issue;

so what happened to UCD3138RJAR

the top mark for this lot of UCD3138RJAR is 6BJ   P1JF  G4
