Part Number: TPS25750

Hello TI,

I want to use TPS25750 in app mode, how it is possible ..?

I plan to just write TX_sink register, there is also some multiple PDO's, how to use PDO..?, because i just want to make enable PPHV.

How i can enable PPHV by using host controller..?

Thanks,

Rahul

Rahul,

The TPS25750 will transition into app mode after it has been booted through I2C or has booted itself from the attached eeprom.

At that point, you can use the host interface to update the supported registers to change and update PDOs.

Rahul,

If you configure the TPS25750 into always enable sink, then it will automatically negotiate a 5V/3A contract and enable PPHV to provide the system with power in order to load the firmware configuration and path that is generated from the config tool.
