Description
The VNQ5E050K-E is a quad channel high-side
driver manufactured in the ST proprietary
VIPower⢠M0-5 technology and housed in the
tiny PowerSSO-24 package.
The VNQ5E050K-E is designed to drive automotive
grounded loads delivering protection, diagnostics
and an 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, 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 VCC 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.
