NCV1124
Dual VariableReluctance
Sensor Interface IC
The NCV1124 is a monolithic integrated circuit designed primarily
to condition signals from sensors used to monitor rotating parts.
The NCV1124 is a dual channel device. Each of the two identical
channels interfaces with a variablereluctance sensor, and
cont i nuous l y compares the sens o r out put si gnal to a
userprogrammable internal reference. An alternating input signal of
appropriate amplitude at IN1 or IN2 will result in a rectangular
waveform at the corresponding OUT terminal, suitable for interface to
either standard microprocessors or standard logic families.
A diagnostic input, common to both channels, provides a means to
test for degradation or loss of the physical connector to both sensors.
Typical Applications
AntiSkid Braking and Traction Control
Vehicle Stability Control
Drive Belt Slippage Detection
Crankshaft/Camshaft Position Sensing
