AS5247U

General Description AS5147U/AS5247U 14-Bit Dual-Die On-Axis Magnetic Rotary Position Sensor with Up to 14-Bit Binary Incremental Pulse Count The AS5147U/AS5247U is a high-resolution redundant rotary position sensor for fast absolute angle measurement over a full 360-degree range. This position sensor is equipped with a revolutionary integrated dynamic angle error compensation (DAEC™) with almost 0 latency at higher rotational speed. For increased signal quality at lower rotational speed, the dynamic filter system (DFS™) reduces transition noise. The robust design of the device suppresses the influence of any homogenous external stray magnetic field. A standard 4-wire SPI serial interface with a CRC protection allows a host microcontroller to read 14-bit absolute angle position data from the AS5147U/AS5247U 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 16384 steps / 4096 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 AS5147U/AS5247U supports embedded self-diagnostics for fulfilling up to ASIL D in safety relevant applications. The AS5247U is using the ams stacked die technology in a TQFP-32 (7x7) package. The AS5147U sensor is available in a TSSOP14 Package. Ordering Inform...
