TPS274C65ASWRHAR TI 4-Channel Smart High-Side Switch | 40-VQFN (6x6) | 65mΩ, 4A

Product Overview

The TPS274C65ASWRHAR from Texas Instruments is a 4-channel smart high-side switch designed for driving resistive, capacitive, and inductive loads. It integrates advanced protection and diagnostic features, making it ideal for harsh automotive and industrial environments. The device operates from a 4.5V to 40V supply and delivers up to 4A 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.
