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.
