This small factor board is fully assembled with AS5600 position sensor and its necessary external components. All relevant signals are available on a dual-row 2.54mm 4-pin header footprint and can be easily wired to an existing application. The AS5600 is a programmable Hall-based rotary magnetic position sensor with a high-resolution 12-bit analog or PWM output for contactless potentiometers. Based on planar Hall technology, this device measures the orthogonal component of the flux density (Bz) from an external magnet while rejecting stray magnetic fields. The default range of the output is 0 to 360 degrees, but the full resolution of the device can be applied to smaller range by programming a zero angle (start position) and maximum angle (stop position). The I²C interface is used for configuration and user programming of non-volatile parameters in the AS5600. Additionally the device can be programmed in 3-wire mode without any programmer. 1.1 Kit Content This kit contains following material listed in Table 1. Additional material can be found on our webpage. Table 1: Kit Content No. Item Description 1 AS5600-SO_EK_AB Adapterboard 2 AS5000-MD6H-1 Reference Magnet 2 Info Find the datasheet online at http://ams.com/eng/AS5000-MD6H-1 Getting Started The AS5600 adapter board is ideal for rapid setup of a contactless potentiometer. Additionally to the adapter board, a sensor magnet in a mechanical setup is required. A reference magnet comes with the kit. 2.1 Adapter Board Pin-Out The pin-out of the adapter board is shown in Table 2. For additional information on the AS5600 pins refer to the product datasheet. www.ams.com Revision 1.3 / 02.12.2014 page 3/10 AS5600-SO_EK_AB Operation Manual Table 2: Adapter Board Pin-Out Header Pin Symbol Description Info J3 1 SCL I2C Clock Use R4 if pull-up is required J3 2 SDA I2C Data Use R4 and R5 if pull-up is required J3 3 GND Ground J3 4 VDD Positive Power Supply J2 1 VRG LDO Pin in 5V Mode Leave open in 5V mode.

Connect the desired pins of the AS5600 using the headers and resistors. Figure 1: Adapterboard Description I2C pull-up resistors Short J1 to operate in 3.3V mode Use 0R for R3 to enable PGO mode www.ams.com Revision 1.3 / 02.12.2014 page 4/10 AS5600-SO_EK_AB Operation Manual 2.3 Mechanical Setup To set up a contactless potentiometer a magnet holder and a magnet are needed to be used with the AS5600 position sensor on a PCB. The configuration is shown in Figure 2. Figure 2: Mechanical Configuration Magnet Holder (non-magnetic) airgap 0.5 - 2.5mm Sensor Magnet (D6x2,5) AS5600 PCB The magnet should be aligned by reading the output of the AGC register of the AS5600. For optimal alignment, the AGC value is in the middle of the AGC range. Note: If the magnetic field seen by the AS5600 is below 8mT, the output is switched off and permanent angle programming is not possible. 2.4 Electrical Setup The adapterboard is many used in following configurations in 5V or in 3.3V mode.: 2.4.1 3-Wire Mode In this mode, the power supply and the output pin of the adapterboard are connected. To program a custom angular output range, short R3 using a 0R resistor to enable the programming option B. Follow the step-by-step instructions in the AS5600 datasheet to program the device. Figure 3: Using the board in 3-Wire Mode + µC - Analog or PWM IN www.ams.com Revision 1.3 / 02.12.2014 page 5/10 AS5600-SO_EK_AB Operation Manual 2.4.2 I2C Mode Using the I2C Interface, all functions of the AS5600 can be configured and permanently programmed. Additionally the output and a raw angle (unmodified value) can be read from the output registers. Figure 4: Using the board in I2C Mode + - µC SDA SCL 3 AS5600 Configuration All options to configure the AS5600 are shown below. The AS5600 operates with a default configuration if no configuration was programmed. 3.1 Programming the output range To adjust a custom angle to the full output range or to modify the Zero Position of the device, the AS5600 must be programmed. Following options are availbale: Progamming start and stop position with I2C (Option A) Progamming start and stop position in 3-Wire Mode (Option B) Programming an angular excursion with I2C (Option C) Follow the step-by-step instructions in the AS5600 datasheet for one of the above programming options. Note: To program only the zero position with Option B, Program an angular excursion of 360deg using Option C first. 3.2 Programming a configuration A configuration must be written using the I2C interface. The Burn_Setting command (Write 0x40 into register 0xFF) can be used to permanently program a configuration. www.ams.com Revision 1.3 / 02.12.2014 page 6/10 AS5600-SO_EK_AB Operation Manual 3.2.1 Low Power Mode Three low power modes are available to reduce the power consumption down to 1,5mA max. 3.2.2 Hysteresis A 1 to 3 LSB hysteresis of the 12-bit resolution can be enabled. 3.2.3 Output selection Per default, the Analog Output is active if a magnet is present. Additionally the Output Pin can be switched to PWM with the option to select a PWM frequency (115Hz,230Hz,460Hz,920Hz) 3.2.4 Slow Filter The slow filter allows improving the output noise. The default setting for the Slow Filter is 16x and can be reduced for faster response. 3.2.5 Fast Filter The fast filter is active by selecting a Fast Filter Threshold. If the output value remains below the threshold, the output noise is defined by the slow filter setting. When exceeding the threshold, the output noise is defined from the fast filter for fast output response. The output noise is again defined by the slow filter as soon as the output stays in the threshold again. 3.2.6 Watchdog If the watchdog is active, the AS5600 automatically enters Low Power Mode 3 after one minute if the output value stays within a threshold of 4 LSB. 4 Board Schematics, Layout and BOM The schematic, layout and BOM of the adapterboard are shown below for reference. 2 4.1 3 4 Schematics The schematic of the board is shown below in Figure 5.
