VNQ860-E

Power Distribution Switches, Load Drivers Overview

The VNQ860-E is a monolithic quad-channel high-side driver realized in STMicroelectronics VIPower M0-3 technology. It drives loads with one side connected to ground, featuring an active current limit, thermal shutdown with automatic restart, and protection against ground pin disconnection. Key electrical parameters include a maximum supply voltage of 41 V, a typical demagnetization voltage of VCC minus 52 V, and a per-channel on-resistance (RDS(on)) of 0.270 Ω at 25°C junction temperature. The device operates within a temperature range of -40°C to +150°C.
