Description
The VN5E050MJ-E is a single channel high-side
driver manufactured in the ST proprietary
VIPower™ M0-5 technology and housed in the
tiny PowerSSO-12 package. The VN5E050MJ-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 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.
