The STMicroelectronics solid-state relay, it is monolithic device developed using VIPower technology, intended to drive four independent resistive or inductive loads with one side connected to ground. Active current limitation prevents dropping of the system power supply in case of shorted load. Built-in thermal shutdown protects the chip from over temperature and short-circuit. The open drain diagnostic output indicates over temperature conditions. Built-in current limiter
