Description
The VND5E160MJ-E is a double-channel
high-side driver manufactured in the ST
proprietary VIPower™ M0-5 technology and
housed in the tiny PowerSSO-12 package. The
VND5E160MJ-E is designed to drive 12 V
automotive grounded loads delivering protection,
diagnostics and easy 3 V and 5 V CMOS
compatible interface 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
auto-restart and overvoltage 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 and
overtemperature indication.
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.
