AS5600-SO_RD_ST

Operation Manual

1         General Description

The reference design allows an easy and fast evaluation of the AS5600 rotary magnetic position

sensor in the lab. Additionally it is possible to replace an existing potentiometer with the AS5600-

SO_RD_ST. The module is fully assembled with and pcb including the AS5600 position sensor and

its necessary external components. All relevant signals are available on a 7-way connector and can

be easily wired to an existing application. Additionally there are tree-pin header to replace existing

potentiometers.

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 without requiring a dedicated programmer.

2.3  Mechanical Setup

The contactless potentiometer reference design comes with the AS5600-SO_RD_ST               PCB

assembled. The PCB holds all necessary components to operate the AS5600 in a contactless

potentiometer application. The configuration of the reference module is shown in Figure 2.

Operation Manual

The magnet is already aligned to get AGC values in the middle of the AGC range.

Note: If the magnetic field seen by the AS5600 would be below 8mT, the output would be switched

off and permanent angle programming would not be possible.

2.4    Electrical Setup

The reference module 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 reference module are connected. To

program a custom angular output range, short R4 using a 0R resistor to enable the programming

option B. Follow the step-by-step instructions in the AS5600 datasheet to program the device.

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.

Operation Manual

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.

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.
