Figure 15. Power Cycling Mode

The optional filter Rx/Cx may again be added to reduce peak currents in the 5V power supply line (see Reducing

Power Supply Peak Currents on page 23).

Polling Mode

Target of this mode is a reduction of the average power consumption. In this mode, the IC supply is pulsed, thereby

reducing the average power consumption to a fraction. The actual angle information and multi turn count value is not

lost; polling mode is especially suited for battery powered applications. The IC is furthermore capable of generating a

WAKE signal as soon as the magnet’s position has changed, but only if the supply of the IC is powered-on again. By

means of the WAKE signal, the system’s power consumption can be further decreased, if certain modules are

activated on demand.
