Description
The VND5E050J-E and VND5E050K-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
VND5E050J-E and VND5E050K-E
designed to drive 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 active low digital status pin is
associated with every output channel in order to
provide Enhanced diagnostic functions including
fast detection of overload and short-circuit to
ground, over temperature indication, short-circuit
to V
diagnosis and on & off-state open-load
CC
detection.
The diagnostic feedback of the whole device can
be disabled by pulling the STAT_DIS pin up, thus
allowing wired-ORing with other similar devices.

1. To ensure long term reliability under heavy overload or short circuit conditions, protection and related
diagnostic signals must be used together with a proper software strategy. If the device is subjected to
abnormal conditions, this software must limit the duration and number of activation cycles.
