Description
The VN808 is a monolithic device designed in
STMicroelectronics VIPower M0-3 technology,
Blo ck Diag r am
intended for driving any kind of load wi th 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 9 ). Non overloaded channels continue to
operate normally. Device automat ically turns OF F
in case of ground pin disconnection. This device is
especially suitable for industrial applications
conform to IEC 61131
