AS5013 − Detailed Description

Power Modes

The AS5013 can operate in two different power modes,

depending on the power consumption requirements of the

whole system.

Readout Cycle Depending on Power Mode (idle bit)

START-UP

After power up and after applying a soft reset (Reg 0Fh [1]) or

hardware reset (RESETn input, LOW pulse >100ns), AS5013

enters the START-UP state. During this state the internal

registers are loaded with their reset values. After min.

Tstartup = 1000μs, the AS5013 will perform one measurement

and switches automatically into the WAIT state.

MEASURE

The Hall element data are measured, x/y coordinates are

calculated and available in registers 10h and 11h after

Tconv = 450μs max.

SET INTERRUPT

The INTn output is set, depending on the interrupt mode

configured in the control register Reg 0Fh [2] and Reg 0Fh [3]

WAIT

The module is now in waiting status. A new measurement will

occur depending on the power mode (Reg 0Fh [7] Idle = 0 or 1)

and the Timebase Reg 0Fh [6:4]
