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.
