Description

The VNQ5E080TD1-E is a quad channel

high-side driver manufactured using ST

proprietary VIPower? M0-5 technology. The

VNQ5E080TD1-E is designed to drive 12 V

automotive grounded loads, and to provide

protection and diagnostics. It also implements a

3 V and 5 V CMOS-compatible interface for use

with any microcontroller.

The device integrates advanced protective

functions such as load current limitation, inrush

and overload active management by power

limitation, overtemperature shut-off with autorestart

and overvoltage active clamp.

A dedicated analog current sense pin is

associated with every output channel providing

enhanced diagnostic functions including fast

detection of overload and short-circuit to ground

through power limitation indication and

overtemperature indication.

The current sensing and diagnostic feedback of

the whole device can be disabled by pulling the

CS_DIS pin high to share the external sense

resistor with similar devices.
