Overview
The VN330SPTR-E, produced by STMicroelectronics, is a monolithic device developed using VIPower technology. It is designed to drive four independent resistive or inductive loads with one side connected to ground. This quad high-side smart power solid-state relay is equipped with advanced protection features and diagnostic capabilities, making it suitable for a variety of industrial applications.
The device incorporates active current limitation to prevent the system power supply from dropping in case of a shorted load. It also features built-in thermal shutdown to protect against overtemperature and short-circuit conditions. The open drain diagnostic output provides real-time monitoring of overtemperature conditions.
