Description
The iC-MP consists of a quadruple Hall sensor array which has been optimized for the magnetic measurement
of an axis angle. The array permits errortolerant adjustment of the magnet, reducing the time and effort required assembly. The integrated signal conditioning unit provides a differential sine/cosine signal at its outputs. The sensor generates one sine
cycle per full rotation of the magnet, enabling the angle to be clearly determined. At the same time the internal amplitude control unit produces a regulated output amplitude of 2 Vpp, regardless of variations in the magnetic field strength, supply voltage and temperature. Furthermore, error signals are provided which report any magnet loss and an excessively
high RPM speed.

Furthermore, error signals are provided which report any magnet loss and an excessively
high RPM speed.
With the aid of the integrated 8-bit sine-to-digital converter the axis angle is determined from the sine/cosine signals. The absolute position angle is output via the serial interface together with a bit indicating an error. The maximum resolution of 8 bits is maintained up to revolutions of 12,000 rpm.
The absolute angle is converted back to a linear analog output voltage using the internal D/A converter. The analog output voltage range can be programmed to be either rail to rail or 10% to 90% of the supply voltage. The angular range of the analog signal is configurable to 90°, 180°, 270° or 360°.
The iC-MP can be easily cascaded, enabling scanning of multiple axes. In Fast Scanning Mode all devices
connected in a queue are read consecutively. In Slow Scanning Mode (Power Save Mode) each individual device is booted up before the serial data or analog output voltage is put on the common bus.
