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 the chip from over temperature. The open

drain diagnostic output indicates over temperature

conditions.
