VN03 ISO high side smart power solid state relay is a monolithic device made using STMicroelectronics Vertical Intelligent Power technology, intended for driving resistive or inductive loads with one side grounded. Built-in thermal shutdown protects the chip from over temperature and short circuit. The open Drain diagnostic output indicates: open load in off state and in on state, output shorted to VCC and overtemperature. Fast demagnetization of inductive loads is archieved by negative (-18V) load voltage at turn-off.
