Product description

The iC-MH8 12-bit angular Hall encoder is a position sensor for scanning a permanent magnet.
The resolution can be configured up to 4096 angular increments per rotation.
The incremental interface with the pins A, B and Z supplies quadrature signals with an edge rate of up to 8 MHz.
The commutation interface with the signals U, V and W provides 120° phase-shifted signals for block commutation of eight pole EC motors.
Sine and cosine signals are externally available to facilitate adjustment.

Features

  • Real-time system for rotation speed up to 120 000 rpm
  • Integrated Hall sensors with automatic offset compensation
  • 4x sensor arrangement for fault-tolerant adjustment
  • Amplitude control for optimum operating point
  • Interpolator with 4096 angular increments/resolution better than 0.1°
  • Programmable resolution, hysteresis, edge spacing, zero position and rotating direction
  • Incremental output of sensor position up to 8 MHz edge rate
  • RS422-compatible AB encoder signals with index Z
  • UVW commutation signals for eight pole EC motor applications
  • BiSS interface for data output and configuration
  • SSI-compatible output mode
  • Integrated ZAP diodes for module setup and OEM data, programmable via BiSS interface
  • Signal error (e.g. magnet loss) can also be read out via BiSS interface
  • Analogue sine and cosine differential signals
  • Extended temperature range from -40 to +125 °C
