VN808 internal block diagram
The VN808 has built-in junction over-temperature
protection which is thermally independent for each of
the eight channels, it has a current limitation (1.1A
typical), and a fast demagnetization block clamped at
–52V typical. Thanks to the built-in protection each
channel is self-protected against load short-circuiting
and overloading. The device is able to manage
large inductive loads, however care must be taken
of the power dissipation related to the switching
frequency in free-wheeling conditions. Both under-
voltage protection and loss of ground protection with
shutdown are added. For the very first time a case
over-temperature protection is integrated into the
VIPower switch. The typical R
DS(on)
of the VN808 is
150m
per channel at 25
°
C, while the operating voltage
is inside the industrial range of 10.5V to 45V.

Double integrated thermal protection exists in VN808
in the form of:
Junction temperature detection (TTSD) and
protection, related to the single channel;
Case temperature detection (TCSD) and protection,
related to the whole device dissipation.
The case temperature protection avoids PCB
degradation if a large number of channels are
overloaded. In fact the TCSD acts only on the
overloaded channel; channels that are not overloaded
continue to operate normally.
10.5 to 36
The VN808 is the first octal single chip high-side
driver developed in VIPower M0-3 technology. Both
the control and power stage use N-MOS technology.
VN808 has 8 different channels with single
protection and diagnostic functions integrated on
a single chip. The VN808 has been developed
considering the needs of the industrial process
control market.
