DESCRIPTION

The V N340SP i s a mono lithic 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.

Note: If INPUT pin is floating the corrisponding channel will automatically switch off. If GND pin is disconnected, the channel will switch off

provided VCC not ex c eed 36V.
