VNI4140KTR-32 ST Power Switch | PowerSO-24 裸露底部焊盘 | 4-Ch, 40V, 1A

Product Overview

The VNI4140KTR-32 is a monolithic quad intelligent power switch manufactured by STMicroelectronics, featuring four independent high-side switches with embedded protection and diagnostic functions. Housed in a PowerSO-24 package with exposed pad for enhanced thermal dissipation, this device is designed for driving resistive, inductive, and capacitive loads in harsh automotive and industrial environments. Each channel can deliver up to 1A continuous current at 40V supply, with integrated overcurrent, overtemperature, and short-circuit protections. The device communicates via a 3.3V/5V compatible SPI interface for real-time diagnostics and control.
