Description
The VN5E010MH-E is a single-channel high-side
driver manufactured in the ST proprietary
VIPower M0-5 technology and housed in the tiny
HPAK package. The VN5E010MH-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.
