Description
AI
The NCV7001 is a four−channel variable reluctance sensorinterface IC. Microprocessor control functions include two polarity5.0 V programmable resets, two programmable watchdog inputs, andan enable function (OLE). Two watchdog inputs allow control fromtwo independent microprocessors.Open sensor detection capability is provided. During test mode(NTEST = Low), a high on the OLE pin should provide a high on theoutput. A low under these conditions indicates an open load.This part has been designed to operate in an automotiveenvironment.
