loads
■ Suitable as LED driver
Description
The VND5E012MY-E is a double channel high-
side driver manufactured in the ST proprietary
VIPower™ M0-5 technology and housed in the
tiny PowerSSO-36 package. The VND5E012MY-E
is designed to drive 12V 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, overtemperature shut-off with auto
restart and over-voltage 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.
