Other Parts Discussed in Thread: TPS22991,
Tool/software:
Hello,
My customer tested the TPS22991 by replacing it with a TPS22917DBVR due to the issue reported in the E2E post below.
RE: TPS22991: Reverse power protection configuration
The QOD and CT pins of TPS22917 are NC processed and TPS22991 is replaced with TPS22917 in the circuit below.
After supplying 1.8V to VCC_1.8VD and measuring the voltage on C639, 1.8V was observed.
Additionally, they tried connecting the ON pin to DGND, but the same symptom was observed.
Is there any configuration they need to add for reverse power protection?
Thank you.
