Description
The VN5E050J-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 VN5E050J-E is designed to drive automotive
grounded loads delivering protection, diagnostics
and easy 3V and 5V 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, 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
CC
diagnosis and ON & OFF state open-load
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.
