Description
The VND5E160AJ-E is a single channel high-side
driver manufactured in the ST proprietary
VIPower M0-5 technology and housed in the tiny
PowerSSO-12 package. The VND5E160AJ-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, over-temperature 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
Ehnanced diagnostic functions including fast
detection of overload and short-circuit to ground
through power limitation indication, overtemperature indication, short-circuit to Vcc
diagnosis and ON & 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.
Stressing the device above the rating listed in the “Absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to the conditions in table below for extended
periods may affect device reliability. Refer also to the STMicroelectronics SURE Program
and other relevant quality document.

3.1 GND protection network against reverse battery
This section provides two solutions for implementing a ground protection network against
reverse battery.

VND5E160AJ-EApplication information
If the calculated power dissipation leads to a large resistor or several devices have to share
the same resistor then ST suggests to utilize Solution 2 (see below).
3.1.2 Solution 2 : diode (D
A resistor (R
=1kΩ) should be inserted in parallel to D

inductive load.
This small signal diode can be safely shared amongst several different HSDs. Also in this
case, the presence of the ground network will produce a shift (≈ 600mV) in the input
threshold and in the status output values if the microprocessor ground is not common to the
device ground. This shift will not vary if more than one HSD shares the same diode/resistor
network.
3.2 Load dump protection
Dld is necessary (Voltage Transient Suppressor) if the load dump peak voltage exceeds the
V
max DC rating. The same applies if the device is subject to transients on the VCC line
CC
that are greater than the ones shown in the ISO 7637-2: 2004(E) table.
3.3 MCU I/Os protection
If a ground protection network is used and negative transient are present on the VCC line,
the control pins will be pulled negative. ST suggests to insert a resistor (R

The value of these resistors is a compromise between the leakage current of µC and the
current required by the HSD I/Os (Input levels compatibility) with the latch-up limit of µC

3.4 Current sense and diagnostic

A logic level high on CS_DIS pin sets at the same time all the current sense pins of the
device in a high impedance state, thus disabling the current monitoring and diagnostic
detection. This feature allows multiplexing of the microcontroller analog inputs by sharing of
sense resistance and ADC line among different devices.
