AMS OSRAM GROUP AS5147-HTSM Magnetic Position Sensor, 14 Bit, TSSOP-14, 4.5 to 5.5 VDC, 1 mA, SMD, AS5147 Series

AS5147-HTSM is a 14-bit on-axis magnetic rotary position sensor with an 11-bit binary incremental pulse count. It is a high-resolution 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 AS5147 and to program non-volatile settings without a dedicated programmer. The AS5147 has been designed to support BLDC motor commutation for the most challenging automotive applications (AEC-Q100 grade 0 automotive qualified) such as electric power steering (EPS), transmission (gearbox, actuator), pump, brake (actuator) and starter and alternator.
