DESCRIPTION
The VN340SP 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.
