The VNI4140K is a monolithic device made using STMicroelectronics VIPower technology, intended to drive 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 conditions, channel turns OFF and back ON automatically so to maintain junction temperature between TTSD and TR. If this condition makes case temperature reach TCSD, overloaded channel is turned OFF and restart only when case temperature has decreased down to TCR. In case of more than one channel in overload, restart of the overloaded channels is not simultaneous, in order to avoid high peak current from the supply. Non-overloaded channels continue operating normally. The open drain diagnostics outputs indicate overtemperature conditions.
