Description
The VN808-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.
VN808-E
Octal channel high side driver
PowerSO-36
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
and TR. If this condition makes case temperature
reach T
, overloaded channel is turned OFF
CSD
and will restart only when case temperature has
decreased down to T
(see waveform 3 Figure 8
CR
on page 11). 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
