Description
The VN808SR is a monolithic device designed in
STMicroelectronics VIPower M0-3 technology,
intended for driving 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 condition,
channel turns OFF and back ON automatically so
as to maintain junction temperature between TTSD
and TR. If this condition makes case temperature
reach TCSD, overloaded channel is turned OFF
and and will restart only when case temperature
has decreased down to TCR( see waveform 3
Figure 7 on page 10). Non overloaded channels
continue to operate normally. Device
automatically turns OFF in case of ground pin
disconnection. This device is especially suitable
for industrial applications conform to IEC 61131
