AS5600 − Register Description
Hysteresis
To avoid any toggling of the output when the magnet is not
moving, a 1 to 3 LSB hysteresis of the 12-bit resolution can be
enabled with the HYST bits in the CONF register.
Magnet Detection
As a safety and diagnostic feature, the AS5600 indicates the
absence of the magnet. If the measured magnet field strength
goes below the minimum specified level (Bz_ERROR), the
output is driven low, without regard to which output mode has
been selected (analog or PWM) and the MD bit in the STATUS
register is 0.
Low Power Modes
A digital state machine automatically manages the low power
modes to reduce the average current consumption. Three low
power modes are available and can be enabled with the PM bits
in the CONF register. Current consumption and polling times
are shown in Figure 6.
Watchdog Timer
The watchdog timer allows saving power by switching into
LMP3 if the angle stays within the watchdog threshold of 4 LSB
for at least one minute, as shown in Figure 36. The watchdog
function can be enabled with the WD bit in the CONF register.
