Description

The VN340SP-E is a monolithic device made using STMicroelectronics VIPower technology, intended for driving four indipendent resistive or inductive loads with one side connected to ground. Active current limitation avoids dropping the system power supply in case of shorted load. Built-in thermal shut-down protects the chip from overtemperature and short circuit. The open drain diagnostic output indicates overtemperature conditions. Each I/O is pulled down when overtemperature condition of the relative channel is verified.
