3 Description

The TPS25762-Q1 is a fully integrated USB Type-

C? Power Delivery (PD) solution with integrated

Buck-Boost converter for automotive single 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).
