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.
