AS5600 − Register Description
Figure 26:
Option C: Programming a Maximum Angular Range Through the I²C Interface
Note(s):
1. After each register command, the new configuration is effective at the output at least 1 ms later.
2. It is recommended to perform a functional test after this procedure.
Output Stage
The OUTS bits in the CONF register are used to choose between
an analog ratiometric output (default) and a digital PWM
output. If PWM is selected, the DAC is powered down.
Without regard to which output is enabled, an external unit can
read the angle from the ANGLE register through I²C interface at
any time.
Use the correct hardware configuration shown in Figure 37 and Figure 38.
Step 1 Power up the AS5600.
Step 2
Use the I²C interface to write the maximum angular range into the MANG register. For example, if
the maximum angular range is 90 degrees, write the MANG register with 0x400.
Configure additional configuration settings by writing the CONFIG register.
Wait at least 1 ms.
Proceed with Step 3 to permanently program the configuration.
Step 3
Perform a BURN_SETTINGS command to permanently program the device.
Wait at least 1 ms.
Step 4
Verify the BURN_SETTINGS command:
Write the commands 0x01, 0x11 and 0x10 sequentially into the register 0xFF to load the actual OTP
content.
Read and verify the MANG and CONF registers to verify that the BURN_SETTINGS command was
successful.
Proceed with Step 5 to permanently program a zero position. If the OUT pin is used for this option, the PGO pin
must be connected to GND.
Step 5 Position the magnet in the start position (zero angle).
Step 6
Pull the OUT pin to GND for at least 100 ms, then allow the pin to float. Alternatively, program the
zero position through the I²C interface (Option A).
Wait at least 1 ms.
Step 7
Verify the permanent programming by I²C (Option A) or check if OUT is permanently driven to GND
(Option B).
Step 8 Read and verify the permanently programmed registers again after a new power-up cycle.
