Texas Instruments TPS25772-Q1 Automotive Dual-Port PD Controller

Texas Instruments TPS25772-Q1 Automotive Dual-Port USB Type-C^™ PD Controller offers an integrated buck-boost converter for automotive dual USB port applications. The TI TPS25772-Q1 functionality includes an integrated buck-boost converter with four power switches, an Arm® Cortex®-M0, and a USB port controller with Type-C cable plug and orientation detection. Additionally, the device incorporates a USB Battery Charging Specification Version 1.2 (BC1.2) detection, USB Endpoint PHY, device power management and supervisory circuitry, 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.
