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