Overview
The VNI2140J is a monolithic device designed using STMicroelectronics' VIPower technology. It is a dual high-side smart power solid state relay that drives two independent resistive or inductive loads, with one side connected to ground. The device features active current limitation to prevent a drop in system power supply in cases of shorted-load, and built-in thermal shutdown to protect the chip from damage due to overtemperature and short-circuit conditions.
