TPS65982EVM setup as type C load

Other Parts Discussed in Thread: TPS25810, TPS65982-EVM, TPS65982-HIUTILITY

Hello Team,

To use TPS65982EVM as load simulator in UFP configuration (while using TPS25810 as DFP), below are some quires.

1.  We connected the Type C cable from DFP board (TPS25810EVM) to this board (J1),  still we need to give power to J4 connector?

2. If we are not providing power on J4 connector then do we need to provide the external 3.3V power to J5 Connector?

3. Where to connect the DC load from this board?

4. Do we have any GUI to set the configurations?

 Pl  guide us for the connection to use this board in UFP configuration. 

Regards,

Mahendra Patel

    The TPS65982-EVM User's Guide shows the configuration ID# options that come pre-installed with the TI EVM FW. You can select the Config ID # by moving the switches on S1.

    J4 does not need to be powered, as the EVM will boot in Dead/No Battery Mode and route power through the PP_EXT FET path as a sink based on the BUSPOWERZ setting (goes to S2, but it is unpopulated so BUSPOWERZ is grounded).

    You can apply a load between J6 and GND. This will allow the overcurrent protection on the PP_EXT FET to turn ON if your load exceeds the USB PD Contract negotiated between the two parts.

    The TPS65982-HIUTILITY is a GUI that allows you to change the configurations in real time, and the TPS6598X-CONIFG is a GUI that allows you to create new FW to overwrite the EVM FW with new default settings saved in NVM memory on the Flash IC. However, when the EVM FW is overwritten, the LED indicators will not necessarily have the same meaning as the labels.
