Description
The VND5E008ASP-E is a double channel
high-side driver manufactured using ST
proprietary VIPower^® M0-5 technology and
housed in PowerSO-16 package. The device is
designed to drive 12 V automotive grounded
loads, and to provide protection and diagnostics.
They also implement a 3 V and 5 V
CMOS-compatible interface for the use 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 providing 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 share
the external sense resistor with similar devices.
