Description
The VND5E050AJ-E and VND5E050AK-E are
double channel high-side drivers manufactured in
the ST proprietary VIPower M0-5 technology and
housed in the tiny PowerSSO-12 and PowerSSO-
24 packages. The VND5E050AJ-E and
VND5E050AK-E are designed to drive 12V
automotive grounded loads delivering protection,
diagnostics and easy 3V and 5V CMOS
compatible interface with any microcontroller.
The devices integrate advanced protective
functions such as load current limitation, inrush
and overload active management by power
limitation, over-temperature shut-off with
auto-restart and over-voltage active clamp. A
dedicated analog current sense pin is associated
with every output channel in order to provide
Enhanced diagnostic functions including fast
detection of overload and short-circuit to ground
through power limitation indication, over-
temperature indication, short-circuit to Vcc
diagnosis and on & off state open load detection.
The current sensing and diagnostic feedback of
the whole device can be disabled by pulling the
CS_DIS pin high to allow sharing of the external
sense resistor with other similar devices.
