c= 25°C

■ 5V logic level compatible input

■ Thermal shutdown

■ Under voltage protection

■ Open drain diagnostic output

■ Inductive load fast demagnetization

■ Very low standby power dissipation

Description

The VN03 is a monolithic device made using

STMicroelectronics Vertical Intelligent Power

technology, intended for driving resistive or

inductive loads with one side grounded. Built-in

thermal shutdown protects the chip from over

temperature and short circuit. The open Drain

diagnostic output indicates: open load in off state

and in on state, output shorted to V

CC

and

overtemperature. Fast demagnetization of

inductive loads is archieved by negative (-18V)

load voltage at turn-off.

2.1 Absolute maximum ratings

Stressing the device above the rating listed in the “Absolute maximum ratings” table may

cause permanent damage to the device. These are stress ratings only and operation of the

device at these or any other conditions above those indicated in the operating sections of

this specification is not implied. Exposure to Absolute maximum rating conditions for

extended periods may affect device reliability. Refer also to the STMicroelectronics sure

program and other relevant quality document.
