Description
The iC-MHL100 is a magnetic position sensor with integrated Hall sensors for the scanning of magnetic tapes and pole wheels featuring a pole pitch of 1mm. Moving speeds of up to 8 m/s can be followed even at highest resolution representing 0.98 ìm. The signal conditioning unit generates constantamplitude sine and cosine voltages that are used for real-time tracking sine-to-digital angle conversion. The resolution can be programmed up to a maximum of 4,096 increments within one magnetic period of 4 mm. The integrated serial interface enables daisy-chain operation of multiple devices with a synchronous position capture at all networked sensors. The device’s memory can also be accessed via the bidirectional BiSS C protocol without interfering the readout cycles. The incremental interface with the pins A, B and Z supplies encoder quadrature signals at an edge rate of up to 8 MHz. Complementary incremental signals are available at the U, V, W outputs. The index position at the Z output is adjustable and can be gated via enable input ENZ. A/B/Z and U/V/W form RS422-compatible outputs and are programmable regarding the output’s drive current and slew rate. A gain-dependent analog signal is available at the GAIN output, which can be used to monitor mechanical alignment of the sensor with respect to the magnetic target. All device parameters can be stored in the internal non-volatile Zener-zapping ROM to allow selfconfiguration after power on. The required writing algorithm for programming is executed by the IC itself. Together with the appropriate magnetic scale or pole wheel, the iC-MHL100 provides a single-chip solution for linear and rotary encoders.
