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 connected to ground.
Block Diagram
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.
