描述 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).
