VN330SPTR-32-E

Power Distribution Switches, Load Drivers Overview

The VN330SPTR-32-E is a monolithic quad high-side smart power solid-state relay developed using STMicroelectronics VIPower technology. It drives four independent resistive or inductive loads with one side connected to ground, operating within a supply voltage range of 10 V to 36 V. Each channel delivers an output current of 700 mA with a typical on-resistance of 200 mΩ. The device features active current limitation to prevent system power supply drops during shorted load conditions and includes built-in thermal shutdown for overtemperature protection. An open-drain diagnostic output indicates fault states, ensuring compliance with IEC 61131-2 standards.
