Part Number: TPS26750
Other Parts Discussed in Thread: BQ25756, BQ25758,

I am trying to play around with the USBCPD Application Customization Tool v 1.1.1 that is web based.

When selecting the TPS26750 and going into advanced configuration, the Export options are all disabled

How do these get enabled?

Hello Marek,

Thank you for reaching out on E2E.

In order to export a configuration using USBCPD Application Customization Tool version 1.1.1 you must fill in the entire questionnaire.

Thank you,

What if I have an application where I do not want the BQ25756 support as the questionarie asks and instead need to ducktape a BQ25758 with a micro?

Marek,

If you are not utilizing a battery charger device, you can select a TPS26750 configuration that does not attach to a BQ device. This will grey out the extra questions at the bottom of the questionnaire. The TPS26750EVM User Guide has more information on the individual questions in the 3 Software Section.

Thank you,

Katilynn

Well that's where my confusion continues. Based on the TPS26750EVM, the "fifth" option with the EPR DCDC block shown should be selectable.

But it always comes up as disabled, with no ability to select it.

There is no mention in the EVM User Guide on additional requirements to enable it that I can find easily

Hi Marek,

The configuration of sourcing 5V/3S is greyed out to due to the configuration not being necessary for many typical designs using the TPS26730.

Can you please provide me with the design applications you require for the TPS26750? Does the PD controller need to provide and/or consume power from the USB-C connector?

Thank you,

Katilynn
