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. Theopen 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 V
