Description
The VND5E050AJ-E and VND5E050AK-E are
double channel high-side drivers manufactured in
the ST proprietary VIPower M0-5 technology and
housed in the tiny PowerSSO-12 and PowerSSO24 packages. The VND5E050AJ-E and
VND5E050AK-E are designed to drive 12V
automotive grounded loads delivering protection,
diagnostics and easy 3V and 5V CMOS
compatible interface with any microcontroller.
The devices integrate 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
Enhanced 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.

Absolute maximum ratings
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

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.

3.1
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 (RGND only)
This can be used with any type of load.
The following is an indication on how to dimension the RGND resistor.
1.
RGND ≤ 600mV / (IS(on)max)
2.
RGND ≥ (−VCC) / (-IGND)
where -IGND is the DC reverse ground pin current and can be found in the absolute
maximum rating section of the device datasheet.
Power dissipation in RGND (when VCC<0: during reverse battery situations) is:
PD= (-VCC)2/RGND
This resistor can be shared amongst several different HSDs. Please note that the value of
this resistor should be calculated with formula (1) where IS(on)max becomes the sum of the
maximum on-state currents of the different devices.
Please note that if the microprocessor ground is not shared by the device ground then the
RGND will produce a shift (IS(on)max * RGND) in the input thresholds and the status output
values. This shift will vary depending on how many devices are on in the case of several
high side drivers sharing the same RGND.
Doc ID 14617 Rev 4
25/44
Application information
VND5E050AJ-E / VND5E050AK-E
If the calculated power dissipation leads to a large resistor or several devices have to share
the same resistor then ST suggests to utilize Section 3.1.2: Solution 2: diode (DGND) in the
ground line.
3.1.2
Solution 2: diode (DGND) in the ground line
A resistor (RGND=1kΩ) should be inserted in parallel to DGND if the device drives an
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
VCC max DC rating. The same applies if the device is subject to transients on the VCC line
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 (Rprot) in line to
prevent the µC I/Os pins to 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:
-VCCpeak/Ilatchup ≤ Rprot ≤ (VOHμC-VIH-VGND) / IIHmax
Calculation example:
For VCCpeak = - 100V and Ilatchup ≥ 20mA; VOHµC ≥ 4.5V
5kΩ ≤ Rprot ≤ 180kΩ
Recommended values: Rprot =10kΩ, CEXT=10nF.
3.4
Current sense and diagnostic
The current sense pin performs a double function (see Figure 33: Current sense and
diagnostic):
●
26/44
Current mirror of the load current in normal operation, delivering a current
proportional to the load one according to a know ratio KX.
The current ISENSE can be easily converted to a voltage VSENSE by means of an
external resistor RSENSE. Linearity between IOUT and VSENSE is ensured up to 5V
minimum (see parameter VSENSE in Table 9: Current sense (8V<VCC<18V)). The
Doc ID 14617 Rev 4
VND5E050AJ-E / VND5E050AK-E
Application information
current sense accuracy depends on the output current (refer to current sense electrical
characteristics Table 9: Current sense (8V<VCC<18V)).
●
Diagnostic flag in fault conditions, delivering a fixed voltage VSENSEH up to a
maximum current ISENSEH in case of the following fault conditions (refer to ):
–
Power limitation activation
–
Over-temperature
–
Short to VCC in off-state
–
Open load in off-state with additional external components.
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.

Short to VCC
A short circuit between VCC and output is indicated by the relevant current sense pin set to
VSENSEH during the device off-state. Small or no current is delivered by the current sense
during the on-state depending on the nature of the short circuit.
Off-state open load with external circuitry
Detection of an open load in off mode requires an external pull-up resistor RPU connecting
the output to a positive supply voltage VPU.
Doc ID 14617 Rev 4
27/44
Application information
VND5E050AJ-E / VND5E050AK-E
It is preferable VPU to be switched off during the module stand-by mode in order to avoid the
overall stand-by current consumption to increase in normal conditions, i.e. when load is
connected.
An external pull down resistor RPD connected between output and GND is mandatory to
avoid misdetection in case of floating outputs in off-state (see Figure 33: Current sense and
diagnostic).
RPD must be selected in order to ensure VOUT < VOLmin unless pulled up by the external
circuitry:
VOUT
Pull − up _ OFF
= RPD ⋅ I L ( off 2) f < VOL min = 2V
RPD ≤ 22 KΩ is recommended.
For proper open load detection in off-state, the external pull-up resistor must be selected
according to the following formula:
VOUT
Pull − up _ ON
=
RPD ⋅ VPU − RPU ⋅ RPD ⋅ I L ( off 2) r
RPU + RPD
> VOL max = 4V
For the values of VOLmin,VOLmax, IL(off2)r and IL(off2)f see Table 10: Open load detection
(8V<VCC<18V).
