DESCRIPTION

The VN450 is a monolithic device made using

SGS-THOMSON

Vertical

Intelligent

Power

Technology, intended for driving resistive or

inductive loads with one side connected to

ground. This device has three independant

channels and three diagnostics.

Built-in thermal shut-down protects the chip from

over temperature and short circuit.

The control inputs are 5V CMOS logic level

compatible.

The open drain diagnostic outputs indicate short

circuit (no load) and overtemperature status.
