TPS55165-Q1: TPS55165-Q1 power-ON/OFF sequencing without PG

Iwata Etsuji

Part Number: TPS55165-Q1

Hi team,

Please do double-check that TPS55165 can be turned OFF with VINP ramping-down properly in the below usecase.

- PS=GND (always normal mode operation)
- IGN = VINP
- IGN_PWRL = GND
- PG = open

Best regards,

Dear Sir,

Yes, when the IGN_PWRL = GND, ramping-down VINP(input voltage) to below UVL can turn off the IC.
