TPS65988: Mosfet switch control

Akash S

Part Number: TPS65988

Hi,

We are working of a USB PD scheme as shown below

At the charger port,

1) If a 9V PDO is negotiated, the external switcher must be enabled and internal switch must be open.

2) If a 5V PDO is negotiated, the internal switch must be closed and the switcher must be disabled.

How to configure the switch operation, based on PDO negotiation?

Hi Akash,

I would suggest to try SRYR to disable 5V sink path, using App config 4CC command, triggered by sink greater than threshold event.

Thanks
