VNI4140K Dual high side smart power solid state relay
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, overloaded 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.
