磁性角度传感器

旋转磁性位置传感器产品系列能够检测旋转轴上两极磁铁围绕 IC 中心旋转时的绝对角度方位。绝对角度位置可以以 PWM、ABI、UVW 等不同方式输出,或通过主机接口直接读取。根据不同应用的要求,提供从 8 位至 14 位的分辨率可选。这种技术可用于高精度角度位置检测、高速旋转系统和无刷直流电机控制(BLDC 电机)。所有旋转磁性位置传感器都可取代绝对或增量式光学传感器以及其他磁性和电感技术、电位计或磁性开关。

AS5047U

The AS5047U 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 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 AS5047U 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 16989 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.
AS5047U are single die sensors and are available in a TSSOP14
Package.

AS5172

The AS5172 is a magnetic position sensor with a high-resolution 12-bit PSI5 output according PSI5 specification Version 1.3 and 2.1.

Based on a Hall sensor technology, this device measures the orthogonal component of the flux density (Bz) over a full-turn rotation and compensates for external stray magnetic fields with a robust architecture based on a 14-bit sensor array and analog front-end (AFE). A sub-range can programmed to achieve the best resolution for the application. To measure the angle, only a simple two-pole magnet rotating over the center of the package is required. The magnet may be placed above or below the device. The absolute angle measurement provides an instant indication of the magnet’s angular position. The AS5172 operates up to a voltage of 16.5V and is protected against overvoltage up to +20V. In addition, the supply pins are protected against reverse polarity up to – 18V.

AS5200L

The AS5200L is an easy to program stacked dual die magnetic rotary position sensor with a high-resolution 12-bit I2C or PWM output. This contactless system measures the absolute angle of a diametric magnetized on-axis magnet. This AS5200L is designed for contactless potentiometer applications and its robust design eliminates the influence of any homogenous external stray magnetic fields.
The industry-standard I2C interface supports simple user programming of non-volatile parameters without requiring a dedicated programmer. By default the output represents a range from 0 to 360 degrees. It is also possible to define a smaller range to the output by programming a zero angle (start position) and a maximum angle (stop position). The AS5200L is also equipped with a smart low power mode feature to automatically reduce the power consumption. This device is designed for automotive applications and is AEC-Q100 grade 1 qualified. To enable safety-critical applications it has two separate sensor dies in one MLF-16 (5x5) package with wettable flanks.

AS5013

The AS5013 is an absolute position sensor for miniature joystick applications with maximum strokes of +/-2.0mm in x- and y-direction based on contactless magnetic sensor technology. To measure xy-movement the sensor needs a simple 2-pole magnet. The absolute xy-position is measured with a resolution of 8 bit = 256 positions and it is provided as a digital value on the serial interface (I²C).

AS5306

The AS5306 is an incremental position sensor for linear and rotary off-axis applications based on contactless magnetic sensor technology. To measure position and motion a multi-pole magnet strip or ring has to be used. There are 160 pulses per 2.4 mm pole pair length on the standardized quadrature output interface with an index pulse (=ABI-interface) with a maximum speed of 15m/s.
