AS5046 Programmable 360° Magnetic Angle Encoder – Preliminary Data Sheet
9.2
The Hall Sensor Front End allows configuration of each Hall Sensor. Each sensor can be disabled or connected to either the
SIN or COS signal bus. Additionally, each sensor can be inverted for differential measurement.
Each Hall Sensor is selected through a device address for the type identifier 0001,
address 000 selects Hall Sensor H0 (see Figure 8)
address 111 selects Hall Sensor H7 (see Figure 8)
Note: If the magnet is placed like shown in Figure 8 the encoder reading will be of zero.
For each Hall Sensor, the corresponding Front End contains 8 bits

Note: When enabling or disabling individual Hall elements to the SIN- and COS- signal buses it is recommended
to allow several milliseconds (typ. 5ms) of dwelling time until the signal is stable and eventual offsets are
compensated.

always set to 0
set to 1 for enabled Hall Elements, set to 0 for disabled Hall Elements
set to 0 for disabled Hall Elements, set to 1 if this Hall Element should be added to the COS signal bus. It
is also possible to enable multiple Hall sensors to this bus
set to 0 for disabled Hall Elements, set to 1 if this Hall Element should be added to the SIN signal bus. It
is also possible to enable multiple Hall sensors to this bus
set to 1 if the Hall Element should be inverted for differential measurement. set to 0 if the Hall Element
should not be inverted
set to 0 for normal operation, set to 1 if the Hall Sensor should be powered down.
