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 overtemperature conditions.
