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 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.

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
