2 / 26 page iC-MH 12-BIT ANGULAR HALL ENCODER Rev C2, Page 2/26 DESCRIPTION The iC-MH 12-bit angular encoder is a position sensor with integrated Hall sensors for scanning a permanent magnet. The signal conditioning unit generates con- stant amplitude sine and cosine voltages that can be used for angle calculation. The resolution can be programmed up to a maximum of 4,096 angular increments per rotation. The integrated BiSS Interface also enables the posi- tion data of several networked sensors to be read out. And the integrated memory can be written embedded in the data protocol. The incremental interface with the pins A, B and Z supplies quadrature signals with an edge rate of up to 8 MHz. Interpolation can be carried out with maximum resolution at a speed of 120,000 rpm. The position of the index pulse Z is adjustable. The commutation interface with the signals U, V and W provides 120° phase-shifted signals for block com- mutation. The zero point of the commutation signals is freely definable in increments of 1.875° over 360°. The commutation signals are available for EC motors with 1 and 2 pole pairs. The RS422-compatible outputs of the incremental interface and the commutation interface are pro- grammable in the output current and the slew rate. In conjunction with a rotating permanent magnet, the iC-MH module forms a one-chip encoder. The entire configuration can be stored in the internal parameter ROM with zapping diodes. The integrated program- ming algorithm is responsible for the writing of the ROM structure. The device described here is a multifunctional iC that contains integrated BiSS C interface components. The BiSS C process is protected by patent DE 10310622 B4 owned by iC-Haus GmbH and its application requires the conclusion of a license (free of charge).
