Application Note

TPS257xx-Q1 Firmware Update With a Host

Abstract

The TPS2576x-Q1 and TPS2577x-Q1 are fully-integrated USB Type-C® Power Delivery (PD) management devices targeting automotive USB Type-C charging applications. For some application scenarios, customers might need to update the firmware for the device. This application note covers the TPS2576x-Q1/TPS2577x-Q1 firmware update process using an embedded device such as an MCU. The TPS2576x-Q1/TPS2577x-Q1 stores the boot and application code on its internal ROM, and is able to accept patch bundles (containing application configuration and code patch) from an external host or EEPROM over I2C.

1 Purpose and Scope

This application note details the TPS2576x-Q1/TPS2577x-Q1 firmware update process. The TPS2576x-Q1/TPS2577x-Q1 firmware, which includes the boot and application code, is stored in the ROM to execute device functionality. The device can then accept patch bundles (containing code patch and application configuration) from an external host or EEPROM over the I2C bus and is stored in the SRAM. The patch bundles can be generated using the TPS2576x-Q1/TPS2577x-Q1 application customization tool (TPS257XX-Q1-GUI on TI's website). To learn more about the GUI, see the TPS257XX-Q1-GUI Configuration Guide.
