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 T TSD and T R . If this

condition makes case temperature reach T CSD , overloaded channel is turned OFF and will restartonly when case temperature has

decreased down to T CR . 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.
