Product description

iC-MP consists of a quadruple Hall sensor array which has been optimized for the magnetic measurement of an axis angle. The integrated signal conditioning unit provides a differential sine/cosine signal at its outputs.
The absolute angle is converted back to a linear analog output voltage that 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°.

Features

  • Hall sensor array with automatic signal control
  • Differential scanning for excellent magnetic stray field tolerance
  • Real-time tracking interpolation of up to 256 angle steps, permitting up to 12 000 rpm
  • Ratiometric output with 0.5 V to 4.5 V or 0 V to 5 V and selectable full-scale angle of 90, 180, 270 or 360 degrees
  • Programmable zero position
  • Fast, serial absolute angle data output
  • Easy daisy chaining of multiple sensors: all analog/digital outputs can be used in buses
  • Loss-of-magnet and excessive frequency indication via error output
  • Non-volatile setup provided by 3x reconfigurable Zener zap ROM
  • 5 V single-supply operation
  • Power-saving standby function
  • Operational temperature range of -40 to +125 °C
  • Space-saving 10-pin DFN package measuring 4 mm x 4 mm

Applications

  • Contactless potentiometer
  • Absolute 360° angle sensor
  • Magnetic rotary encoders
