Texas Instruments TPS25762-Q1 Automotive Power Delivery Controller

Texas Instruments TPS25762-Q1 Automotive USB Type-C® Power Delivery Controller integrates a Buck-Boost converter for automotive single USB port applications. The TI TPS25762-Q1 functionality includes an integrated buck-boost converter with four power switches, an Arm® Cortex®-M0, a USB port controller with a Type-C cable plug, and orientation detection. Additionally, the device incorporates 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 provided USB power while protecting the system from automotive battery transient and over-temperature conditions.
