Description
The VN808CM is a monolithic device designed
with STMicroelectronics VIPower M0-3
Technology, and is intended for driving any kind of
load with one side co nnec ted to ground.
Blo ck Diag r am
It can be driven by using a 3.3V logic supply.
Active current limitation, combined with thermal
shutdown and automatic restart, protect the
device against overload. In overload condition,
the channel turns OFF, then back ON
automatically so as to maintain junction
temperature between TTSD and TR. If this
condition makes the case temperature reach
TCSD, the overloaded channel is turned OFF and
will restart only when the case temperature has
decreased down to TCR (see Figures 6-7).
Channels that are not overloaded continue to
operate normally.
The device automatically turns OFF when the
Ground pin is disconnected. This device is
especially suitable for industrial applications
which conform to IEC 61131 (Programmable
Controllers International Standard)S
