Description
The VN808CM-E is a monolithic device designed
in STMicroelectronics VIPower M0-3 technology,
intended for driving any kind of load with one side
connected to ground.

PowerSO-36
It can be driven by using a 3.3 V logic supply.
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 T_TSD
and T_R. If this condition makes case temperature
reach T_CSD, overloaded channel is turned OFF
and will restart only when case temperature has
decreased down to T_CR(see waveform 3 Figure 6
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.
