STEVAL-IFP002V1
Applications
This reference design boards is an industrial
application of the ST high side drivers VN808 .
The boards respect international standards of the
electromagnetic compatibility as well as immunity
tests. They have been tested at different typical
ambient temperatures. The reference design is
suitable for use in Programmable Logic
Controllers to produce the related digital outputs
according to IEC standards.
Circuit description
In order to protect the high-side driver (HSD) from
the harsh industrial conditions of power supply
lines, usually optocouplers and Transil diodes are
used to separate the application control circuits
from the power supply. The VN808 reference
design board uses multi-channel optocouplers
suitable for surface-mounted assemblies that
consist of a photo transistor optically coupled to a
gallium-arsenide infrared emitting diode. The
isolation voltage for this type of optocoupler is
2500 V
RMS
. The clamping function of Transil
diodes protect the HSD against transient
overvoltages. The reference design board is
assembled with uni-directional Transil diodes
because they protect the HSD against both
positive and negative surge pulses.
