TPS274C65ASRHAR TI Power Switch | 40-VQFN (6x6) | 65mOhm, 4-Channel

Product Overview

The TPS274C65ASRHAR is a 4-channel smart high-side power switch from Texas Instruments, designed for robust control of resistive, inductive, and capacitive loads. It integrates advanced protection features and diagnostics, making it ideal for harsh automotive and industrial environments. The device operates over a wide input voltage range of 4V to 40V and delivers up to 2A per channel with a typical on-resistance of 65mΩ. Housed in a compact 40-pin VQFN (6x6mm) package, it offers high power density and thermal performance.
