Dear TI team
Please tell me about the operation when "TPS25750D" is used as a 5V/2A sink PDO in a dedicated sink machine.
I think the switch separating VBUS and PPHV is turned on after negotiation with the source device.
I understand that the following order works, is this correct?
①Connect the "TPS25750D" board to the source device using a type-c cable
②When VBUS is supplied, the TPS25750 generates LDO_3V3 and LDO_1V5 for the external EEPROM and supplies power.
③Load PDO configuration written in EEPROM
④After negotiation with the source device, the PPHV switch is turned on and VBUS and PPHV are shorted.
⑤Power is supplied to the system connected to the PPHV pin of the TPS25750D
Best Regards,
Taroimo
