Description
The VN808-E is a monolithic device, realized in
STMicroelectronics VIPower M0-3 technology,
intended to drive any kind of load with one side
connected to ground. Active current limitation
combined with thermal shutdown and automatic
restart, protect the device against overload. In
overload conditions, the channel turns OFF and
ON again automatically in order to maintain the
junction temperature between T
TSD
and T
R
. If
this
condition makes case temperature reach T
CSD
,
overloaded channels are turned OFF and restart
only when case temperature decreases down to
T
CR
. Non-overloaded channels continue to
operate normally. The device automatically turns
OFF in case of ground pin disconnection. This
device is especially suitable for industrial
applications conform to IEC 61131.
