AS5600 − Detailed Description

increment of the calculated angle. If the DIR pin is connected

to VDD (DIR = 1) an increment of the calculated angle will

happen with counterclockwise rotation.

Figure 35:

Raw Angle in Clockwise Direction

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

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.
