Description
– Very low standby current
The VND5025BK-E is a monolithic device made
using STMicroelectronics VIPower™ M0-5
technology, intended for driving resistive or
inductive loads with one side connected to
– 3.0V CMOS compatible input
– Optimized electromagnetic emission
– Very low electromagnetic susceptibility
– In compliance with the 2002/95/EC
ground, and suitable for driving LEDs. Active V
CC
european directive
pin voltage clamp protects the device against low
energy spikes (see ISO7637 transient
– Two classes with different ‘K@3A’ ranges
– Package: ECOPACK®
■ Diagnostic functionsDoc ID 13374
– 3Acurrent sense precision of +/-8%
– Proportional load current sense
compatibility table). This device integrates an
analog current sense which delivers a current
proportional to the load current (according to a
known ratio) when CS_DIS is driven low or left
open. When CS_DIS is driven high, the
CURRENT SENSE pin is in a high impedance
condition. Output current limitation protects the
device in overload condition. In case of long
overload duration, the device limits the dissipated
power to safe level up to thermal shutdown
intervention. Thermal shutdown with automatic
restart allows the device to recover normal
operation as soon as fault condition disappears.
– High current sense precision for wide range
currents
– Current sense disable
– Thermal shutdown indication
– Very low current sense leakage
■ Protection
– Undervoltage shutdown
– Overvoltage clamp
– Load current limitation
– Self-limiting of fast thermal transients

1. To ensure long term reliability under heavy overload or short circuit conditions, protection and related
diagnostic signals must be used together with a proper software strategy. If the device is subjected to
abnormal conditions, this software must limit the duration and number of activation cycles.

GND protection network against reverse battery
This section provides two solutions for implementing a ground protection network against
reverse battery.
3.1.1
Solution 1: resistor in the ground line (R
only)
GND
This first solution can be used with any type of load.
The following formulas indicate how to dimension the R
resistor:

1.
2.

is the DC reverse ground pin current and can be found in the absolute

This resistor can be shared among several different HSDs. Please note that the value of this
resistor is calculated with formula (1), where I
state currents of the different devices.
becomes the sum of the maximum on-
S(on)max
Please note that if the microprocessor ground is not shared by the device ground, the R
GND
produces a shift (I
* R
) in the input thresholds and the status output values. This
S(on)max
GND
shift varies depending on how many devices are ON in the case of several high-side drivers
sharing the same R
.
GND
22/32
Doc ID 13374 Rev 4
VND5025BK-E
Application 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 the following Solution 2.
3.1.2
Solution 2: diode (D
) in the ground line
GND
If the device drives an inductive load, insert a resistor (R
= 1kΩ) in parallel to D
.
GND
GND
This small signal diode can be safely shared among several different HSDs. Also in this
case, the presence of the ground network produces 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 does not vary if more than one HSD shares the same diode/resistor
network.
3.2
3.3
Load dump protection
D is necessary (Voltage Transient Suppressor) if the load dump peak voltage exceeds the
ld
V
maximum DC rating. The same applies if the device is subject to transients on the V
CC
CC
line that are greater than the ones shown in the ISO 7637-2:2004E table.
MCU I/Os protection
If a ground protection network is used and negative transients are present on the V line,
CC
the control pins are pulled negative. ST suggests to insert an in-line resistor (R ) to
prot
prevent the µC I/Os pins from latch-up.
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
I/Os.
