Socket Board for AS5247

The AS5247 is a high-resolution redundant rotary position sensor for fast absolute angle measurement over a full 360-degree range. This new position sensor is equipped with a revolutionary integrated dynamic angle error compensation (DAEC™) with almost 0 latency. The robust design of the device suppresses the influence of any homogenous external stray magnetic field. A standard 4-wire SPI serial interface allows a host microcontroller to read 14-bit absolute angle position data from the AS5247 and to program non-volatile settings without a dedicated programmer. Incremental movements are indicated on a set of ABI signals with a maximum resolution of 2048 steps / 512 pulses per revolution. The resolution of the ABI signal is programmable to 1024 steps / 256 pulses per revolution. Brushless DC (BLDC) motors are controlled through a standard UVW commutation interface with a programmable number of pole pairs from 1 to 7. The absolute angle position is also provided as PWM-encoded output signal. The AS5247 supports embedded self-diagnostics including magnetic field strength too high, magnetic field strength too low or lost magnet, and other related diagnostic features. The AS5247 is available as a dual die in a compact MLF-40 7x7 package.

The USB Interface & Programmer Box is an universal evaluation tool for magnetic position sensors with I2C or SPI interface. It comes with a 10-way cable to connect to a supported product on an existing board. The I2C or SPI wires are used for the communication (3.3V mode) and additionally the sensor can be powered from the USB I&P Box. By using the USB I&P Box Software, it is possible to read out the sensor data, write a configuration and to permanently program a configuration.

Hardware and Software requirements: PC with Windows 7 or later and a USB-A port
