Overview
The VN340SPTR-E is a monolithic device developed using STMicroelectronics' 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 part of the VN340SP-E and VN340SP-33-E family, offering advanced protection and control features. The device includes active current limitation to prevent the system power supply from dropping in case of a shorted load, and built-in thermal shutdown to protect against overtemperature and short-circuit conditions. The open drain diagnostic output indicates overtemperature conditions, enhancing system reliability and safety.
