7.4 Power Modes

The AS5013 can operate in two different power modes, depending on the power consumption requirements of the whole system.

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]
