Description
The VND5E160ASO-E is a single channel high-
side driver manufactured using ST proprietary
VIPower^® M0-5 technology and housed in
SO-16L package. The device is designed to drive
12 V automotive grounded loads, and to provide
protection and diagnostics. It also implements a
3 V and 5 V CMOS-compatible interface for 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.
