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.
Features
•Four Channel Capability
•Differential Inputs
•Open Sensor Detect
•5.0 V Supply Operation with RESET and Watchdog Features
•On-Chip Input Voltage Clamping
•NCV Prefix for Automotive and Other Applications Requiring Site
and Change Control
•AEC Qualified
•PPAP Capable
•Pb-Free Packages are Available*
Typical Applications
•Antilock Braking Systems (ABS)
•Traction Control Systems (TCS)
•Vehicle Dynamics Control (VDC)
*For additional information on our Pb-Free strategy and soldering details, please
