Overview
The VN340SP-33-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 particularly useful in applications requiring robust and reliable load management. The device features active current limitation to prevent system power supply drop in case of shorted loads and built-in thermal shutdown to protect against overtemperature and short-circuit conditions. An open drain diagnostic output indicates overtemperature conditions, enhancing the device's reliability and safety.
