loads
■ Suitable as LED driver
Description
The VND5E050MCJ-E and VND5E050MCK-E
are double channel high-side drivers
manufactured using ST proprietary VIPower
M0-5 technology and housed in PowerSSO-12
and PowerSSO-24 packages. The devices are
designed to drive 12 V automotive grounded
loads, and to provide protection and diagnostics.
They also implement a 3 V and 5 V CMOScompatible interface for the use with any
microcontroller.
The devices integrate advanced protective
functions such as load current limitation, inrush
and overload active management by power
limitation, overtemperature shut-off with
auto-restart 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.
