NCV7001

Quad Variable Reluctance

Sensor Interface IC

The NCV7001 is a four−channel variable reluctance sensor

interface IC. Microprocessor control functions include two polarity

5.0 V programmable resets, two programmable watchdog inputs, and

an enable function (OLE). Two watchdog inputs allow control from

two independent microprocessors.

Open sensor detection capability is provided. During test mode

(NTEST = Low), a high on the OLE pin should provide a high on the

output. A low under these conditions indicates an open load.

This part has been designed to operate in an automotive

environment.
