Description
The VN540-E, VN540SP-E, VN540-12-E are
monolithic
devices
designed
in
STMicroelectronics VIPower technology, intended
for driving resistive or inductive loads with one
side connected to ground. Active current limitation
avoids the system power supply dropping in case
of shorted load. Built-in thermal shut-down
protects the chip from overtemperature. The open
drain diagnostic output indicates over-
temperature conditions.
