3 Description

The TPS25772-Q1 is a fully integrated dual-port USB

Type-C® Power Delivery (PD) solution with integrated

buck-boost converter for automotive dual USB port

applications. Functionality includes: integrated Buck-

Boost converter with 4 power switches; an ARM®

Cortex®-M0; USB port controller with Type-C cable

plug and orientation detection; USB Battery Charging

Specification Version 1.2 (BC1.2) detection; USB

Endpoint PHY; device power management and

supervisory circuitry; and connector pin protection

over-voltage and short-circuit protection;

An intelligent System Policy Manager maximizes

delivered USB power while protecting the system from

automotive battery transient and over-temperature

conditions.

Device configuration settings are selected through an

intuitive graphical user interface (GUI).
