DESCRIPTION
The VN540, VN540SP, VN540(011Y),
VN540(012Y) is a monolithic device 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 thechip fromover temperature. The open
drain diagnostic output indicates over temperature
conditions.

Note 1: The input voltage is internally clamped at 32V minimum, it is possible to connect the input pins to an higher voltage via an external
resistor calculate to not exceed 10mA.
Note 2: If INPUT pin is floating the corresponding channel will automatically switch off. If GND pin is disconnected, the channel will switch off
provided VCC not exceed 36V.
