Does TPS25750 maintain IDLE SINK MODE at the following conditions?

[Conditions]

- CC attached & No new activity for T

- PP_5V has no voltage supply

- VIN_3V3 has 3.3V

Hide,

PP_5V and VIN_3V3 are not required to operate in Sink Mode.

If CC is attached and PD is negotiated, then the TPS25750 will maintain the negotiated contract, but if no PD negotiation occurs, then the TPS25750 will attach as a type C non PD peripheral in this state.

It is generally not a good practice to provide VIN_3V3 and not PP_5V. These two supplies are almost always conencted together.

Chuk
