Abstract

The TPS25751 and TPS26750 are configurable USB Type-C® and Power Delivery (PD) controllers optimized for applications supporting power. In general, these PD controllers use I2Cc to load a binary image from an external EEPROM during boot. If an embedded controller (EC) is available, then the EC can be used in place of an EEPROM to load the image to the PD through the I2Ct interface. The technical reference manuals (1 and 2) demonstrate the flow for writing the image to the PD over the I2Ct Bus to multiple PD controllers at the same time. This application note describes this flow in greater detail and focuses on writing the image to one PD controller. A step-by-step explanation for the PTCH mode to APP mode transition by using an I2C command through I2Ct is provided along with example code.
