iC-MH
12-BIT ANGULAR HALL ENCODER
FEATURES
• Real-time system for rotation speed of 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 of up to 8 MHz edge rate
• RS422-compatible AB encoder signals with index Z
• UVW commutation signals for 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 be read out via BiSS
interface
• Extended temperature range from -40 to +125 °C
