... V out CC ( Description The VNI2140J is a monolithic device designed using STMicroelectronics' VIPower technology. The device drives two independent resistive or inductive loads with one side connected to ground. Active current limitation prevents a drop in system power supply in cases of shorted-load, and built- in thermal shutdown protects the chip from damage due to over-temperature and short- circuit ...
