The VNI4140K-32 is a monolithic device made using STMicroelectronics VIPower technology, intended to drive four independent resistive, capacitive or inductive loads with one side connected to ground. Active current limitation avoids the system power supply dropping in case of shorted load. Built-in thermal shutdown protects the chip from overtemperature and short-circuit. In overload conditions, the channel turns OFF and back ON automatically so to maintain junction temperature between TTSD and TR. If this condition causes case temperature to reach TCSD, the overloaded channel is turned OFF and restarts 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 diagnostic outputs indicate overtemperature conditions.
