Overview
The VN330SP-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 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. Additionally, it includes an open drain diagnostic output to indicate overtemperature conditions and supports fast demagnetization of inductive loads, conforming to IEC 61131-2 standards.
