iC-MHM
14-BIT ABSOLUTE ANGLE HALL ENCODER
FEATURES
• Quad Hall sensor array for easy assembly
• Monitored auto-gain control, optional fine-calibration for
compensation of misalignment
• Absolute resolution of 0.02 ° (14 bit / 360 ° at up to 10 000 rpm)
• Selectable resolution and tracking rate (12 bit at 80 000 rpm)
• Adjustable zero position and code direction
• Differential current-limited sin/cos outputs (1 Vpp into 100 Ω)
• BiSS Interface for CRC-secured communication
• Compatible with BiSS C profiles (BP1, BP3) and SSI
• Integrated RS422 transceiver for up to 10 Mbit/s (at 5 V)
• Higher data rates supported by LVDS compatibility
• System monitoring via BiSS error/warning bits (loss-of-magnet)
• Multiturn input via dedicated SSI MT interface (up to 32 bits)
• Command/pin-triggered position preset for ST/MT data
• 3 General-Purpose I/Os; open-drain error output
• SPI operation optional
• CRC-protected EEPROM setup (multi-master I²C interface)
• Extended temperature range from -40 to +125 °C
• Reverse-polarity and short-circuit-proof interface pins
