Description
The VND5E050ACJ-E and VND5E050ACK-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 CMOS-compatible interface for 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, overtemperature
indication, short-circuit to V_CC diagnosis on-state
and 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 share the external sense
resistor with similar devices.
