TPS25832QWRHBTQ1

Power Management - Specialized Overview

The TPS25832QWRHBTQ1 is an automotive-grade USB Type-C and BC1.2 charge port converter designed for high-voltage input applications. It integrates a synchronous step-down converter delivering a regulated 5-V output at up to 3.5 A, supporting inputs from 4.5 V to 36 V. Qualified under AEC-Q100 standards with Temperature Grade 1, it operates reliably across a junction temperature range of -40°C to +125°C. The device features cable compensation technology to maintain accurate voltage regulation at the load despite line losses. Packaged in a VQFN-32 format, it includes integrated protection mechanisms against overcurrent, overvoltage, and thermal events.
