1 Introduction

This application note explains the key USB Type-C control, DP pin assignment configuration, and signal tuning working flow for TUSB1044 with TI PD controller TPS6598X and TPS6599X family.

The TI PD controller TPS6598X and TPS6599X families are highly-integrated PD controller solutions with two power switches integrated for sink and source (TPS6598X) or source (TPS6599X) power paths and compliant for PD3.0 operation. The PD controller acts as a primary and configures the TUSB1044 in the GPIO or the I²C mode depends on the CC and PD communication of the PD controller.

For host (source) or device (sink) applications, the TUSB1044 enables a USB/DP compliant system to pass both USB/DP transmitter electrical compliance and USB receiver jitter tolerance tests.
