VNI4140K-32 ST Power Switch | PowerSSO-24 | 4-Channel, 40V, 1A

Product Overview

The VNI4140K-32 is a monolithic, four-channel high-side smart power switch manufactured by STMicroelectronics. It integrates control logic, protection features, and power MOSFETs in a single PowerSSO-24 package. Designed for driving resistive, inductive, and capacitive loads, it provides robust protection against overcurrent, overtemperature, and short-circuit conditions. The device operates from a 10V to 36V supply voltage and delivers up to 1A per channel (continuous) with a typical on-resistance of 400mΩ per channel. Its diagnostic feedback via open-drain outputs enables real-time monitoring of load status and fault conditions.
