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 and 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.
