AS5601 − Register Description

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.

In a low-power mode, the fast filter is automatically disabled,

because there is no need for a fast settling time if the output

refresh is as fast as the polling cycles.

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 32. The watchdog

function can be enabled by setting the WD bit in the CONF

Figure 32:
