... Two diagnostic outputs are provided to indicate an out-of- range condition of the magnetic field as well as movement of the magnet in Z-axis. In addition a specific combination of output states indicate a loss of power supply. The AS5035 is available in a small 16pin SSOP package. It can be operated at either 3. supplies.

... AS5035 – 64 PPR INCREMENTAL MAGNETIC ROTARY ENCODER 5.5 MagInc and MagDec Indicators These two pins are open-drain outputs with a maximum driving capability of 2mA @ 3.0V and 4mA @ 4.5V. MagINC, (Magnitude Increase) turns on, when the magnet is pushed towards the IC, thus when the magnetic field strength is increasing ...

... Any position within a full turn can be defined as the permanent new index position. Figure 6: Hardware connection of AS5035 to AS50xx Demoboard for Zero Position Programming Revision 1.5 For Zero Position Programming, the magnet is turned to the mechanical zero position (e.g. the “off”-position of a rotary switch) and an automatic zero position programming is applied ...

... CCW-bit (see Figure 7) allows for reversing the indicated direction, e.g. when the magnet is placed underneath the IC: CCW = 0 – angular value increases clockwise; CCW = 1 – angular value increases counterclockwise. Note: Further information on the required hardware and software for Zero Position programming of the AS5035 can be found in austriamicrosystems website: http:www.austriamicrosystems.com ...

... Figure 9: Arrangement of Hall sensor array on chip (principle) With reference to Figure 9, a diametrically magnetized permanent magnet is placed above or below the surface of the AS5035. The chip uses an array of Hall sensors to sample the vertical vector of a magnetic field distributed across the device package surface. The area of magnetic sensitivity is a circular locus of 1 ...

... AS5035 – 64 PPR INCREMENTAL MAGNETIC ROTARY ENCODER The magnet’s field strength perpendicular to the die surface should be verified using a gauss-meter. The magnetic field given distance, along a concentric v circle with a radius of 1.1mm (R1), should be in the range of ±45mT…±75mT. (see Figure 10). ...

... High Speed Operation 10.3.1 Sampling Rate The AS5035 samples the angular value at a rate of 10k samples per second. Consequently, the incremental outputs are updated each 100µ stationary position of the magnet, this sampling rate creates no additional error ...

... Temperature 10.5.1 Magnetic Temperature Coefficient One of the major benefits of the AS5035 compared to linear Hall sensors is that it is much less sensitive to temperature. While linear Hall sensors require a compensation of the magnet’s temperature coefficients, the AS5035 automatically compensates for the varying magnetic field strength over temperature. The magnet’ ...
