1 / 40 page  ams Datasheet Page 1 [v1-01] 2015-May-12 Document Feedback AS5147P 14-Bit On-Axis Magnetic Rotary Position Sensor with 12-Bit Binary Incremental Pulse Count and for 28krpm High Speed Capability The AS5147P is a high-resolution rotary position sensor for high speed (up to 28krpm) 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 AS5147P 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 4096 steps / 1024 pulses per revolution. The resolution of ABI signal is programmable to 4096 steps / 1024 pulses per revolution, 2048steps / 512 pulses per revolution or 1024steps / 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 AS5147P supports embedded self-diagnostics including magnetic field strength too high, magnetic field strength too low or lost magnet, and other related diagnostic features. The product is defined as SEooC (Safety Element out of Context) according ISO26262 including FMEDA, safety manual and third party qualification. The AS5147P is available as a single die in a compact 14-pin TSSOP package. Ordering Information and Content Guide appear at end of datasheet. Key Benefits & Features The benefits and features of this device are listed below: Figure 1: Added Value of Using the AS5147P Benefits Features High speed application Up to 28krpm Easy to use – saving costs on DSP DAEC™ Dynamic angle error compensation General Description |
