TPS25750: How to set configuration via I2C?

Roy Chou1

Part Number: TPS25750

Hi Team,

We would like to set below configuration in TPS25750. But I have no idea how to config below setting by register and I couldnt find the register status in GUI page.

May you let me know how to set? And we need you to review our schematic. Due to confidential material, may you provide the email address that I could send it to you directly?

Thank.

sink only 20V 100W

Roy,

We provide a FAQ that describes the exact cast that you are looking to implement: [FAQ] TPS25750: How do I create a PD UFP or Sink with an EEPROM?

This will show you to to create and review your schematic.

The method that we use to generate the EEPROM binary file is described in GUI quick start guide: TPS25750EVM Quick Start Guide (Rev. A)

If you have a MCU in the system and plan to interface to the TPS25750, this interface is documented in the TPS25750 Application Customization Tool User's Guide

Regards,

Chuck

Hi Chuck,

Thanks for information.

This is my 1st time to use this device. I may need to ask you more detailed. After I set the config to TPS25750EVM by using GUI, I assume that I could get the register setting like set address and its data content. I only could gen the bin file, but I have no idea what the file is.

In APP note, I couldn't find related information. May you let me know which part should I review?

If i have any misunderstanding, please let me know, thanks.

Roy,

The I2C interface is not a simple I2C interface. There are a combination of commands and registers. They are all described in the TPS25750 Host Interface Technical Reference Manual

You are not required to use the I2C interface for control at all unless you want or need more specific control over behavior. The TPS25750 is designed to be fully autonomous once configured.

Regards,

Chuck
