VNI4140KTR ST PowerSSO-24 | Quad High-Side Driver | 40V, 1.4A

Product Overview

The VNI4140KTR is a monolithic quad high-side smart power solid-state relay manufactured by STMicroelectronics, housed in a compact PowerSSO-24 package. It integrates four independent high-side switches with advanced protection features, making it ideal for driving resistive, inductive, and capacitive loads in automotive and industrial applications. The device operates from a 10V to 36V supply voltage and delivers up to 1.4A per channel (continuous) with a typical on-resistance of 0.35Ω. Its robust design includes overcurrent, overtemperature, and short-circuit protection, as well as a diagnostic output for fault reporting.
