Abstract

The TPS25751 is a highly integrated stand-alone USB Type-C® and Power Delivery (PD) controller optimized for applications supporting USB-C PD Power. In general, the TPS25751 loads the patch file by EEPROM initially when powering on the device. If there is no EEPROM, the system needs to use EC (Embedded Controller) to issue patch file to I2Ct. The TPS25751 Technical Reference demonstrates the flow for Pushing a Patch Bundle Over the I2Ct Bus to Multiple PD Controllers at the same time, but can be hard to understand. This application note demonstrates the step-by-step explanation for PTCH mode to APP mode transition by using I2C command through I2Ct and also shows the commonly used function in TPS25751.
