Description
The VNI4140K is a monolithic device made using
STMicroelectronics VIPower technology, intended
for driving four independent resistive or inductive
loads with one side connected to ground. Active
current limitation avoids dropping the system
power supply in case of shorted load. Built-in
thermal shutdown protects the chip from
overtemperature and short-circuit. 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,
overloadedwww.DataSheet.net/ channel is turned OFF and will
restartonly when case temperature has
decreased down to TCR. In case of more than one
channel in overload, re-start of the overloaded
channels will not be simultaneous, in order to
avoid high peak current from the supply. Non
overloaded channels continue to operate
normally. The open drain diagnostics outputs
indicates overtemperature conditions.
