Overview
The VNQ860SP-E is a quad-channel high-side driver produced by STMicroelectronics, realized in the VIPower M0-3 technology. This monolithic device is designed to drive various types of loads with one side connected to ground. It features active current limitation, thermal shutdown with automatic restart, and protection against overload. The device automatically turns OFF in case of ground pin disconnection, making it particularly suitable for IEC 61131 compliant industrial applications.
