Power modes

The AS5011 can operate in three different power modes, depending on the power consumption requirements of the

whole system.

Power Mode

[0x76] Register

Description

Sleep phase

Power state between wakeups in Shutdown and Low Power modes

RC clock and analog part OFF

Digital part in static mode

Shutdown mode

1001_x00x

LP_Pulsed = 1

LP_Active = 0

LP_Continue =

0

INT_wup_en =

1

Default mode after power on

<50µA current consumption

Wake up every 80ms from Sleep phase

Hall elements in reduced power during wake up

RC clock ON

Interrupt LOW on INTn if the magnet is away from the center above the

Xp Xn Yp Yn threshold values (1)

Low Power mode

110x_100x

LP_Pulsed = 1

LP_Active = 1

LP_Continue =

0

INT_act_en = 1

<200µA current consumption

Wake up every 20ms from Sleep phase

Hall elements in high power during wake up for better accuracy

RC clock ON

Interrupt LOW on INTn when XY coordinates are ready to be read (1)

Full Power mode

LP_Pulsed = 0

LP_Active = 1

LP_Continue =

0

<8mA current consumption

Continuous read

Hall elements in high power permanently

RC clock ON

Interrupt LOW on INTn when XY coordinates are ready to be read (1)

If INT_act_en = 1, after reading the XY coordinate, the next sample is

stored and won’t be updated until the next read of XY with interrupt

release.

If INT_act_int_en = 0, the last converted XY coordinate is read in real

time.

(1) The interrupt will be released to HIGH by reading the X_res_int or Y_res_int registers, or by switching the

device into a different power mode.
