VN920
Single channel high-side solid-state relay
Features
■CMOS compatible input
■Proportional load current sense
■Shorted load protection
■Under-voltage and over-voltage shutdown
■Over-voltage clamp
■Thermal shutdown
■Current limitation
■Protection against loss of ground and loss of
VCC
■Very low standby power dissipation
■Reverse battery protected (see Application
schematic )
Description
The VN920 is a monolithic device designed in
STMicroelectronics VIPower M0-3 technology.
The VN920 is intended for driving any type of load
with one side connected to ground. The active
VCC pin voltage clamp protects the device against
low energy spikes (see ISO7637 transient
compatibility table). Active current limitation
combined with thermal shutdown and automatic
restart protects the device against over-load.
The device integrates an analog current sense
output which delivers a current proportional to the
load current. The device automatically turns off in
the case where the ground pin becomes
disconnected.

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

3 Application information
Figure 19. Application schematic
3.1 GND 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.
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 (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.
Series resistor in INPUT and STATUS lines are also required to prevent that, during battery
voltage transient, the current exceeds the absolute maximum rating.
Safest configuration for unused INPUT and STATUS pin is to leave them unconnected.
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 ≤ 65kΩ.
Recommended values: Rprot =10kΩ .
