Description
The VND5E025AK-E is a double channel high-
side driver manufactured in the ST proprietary
VIPower M0-5 technology and housed in the tiny
PowerSSO-24 package. The VND5E025AK-E is
designed to drive 12 V 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, 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, overtemperature
indication, short-circuit to V
CC
diagnosis and
on-state and off-state open-load detection. 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.
