7 Detailed Description

The benefits of the AS5013 device are as follows:



Complete system-on-chip



High reliability due to non-contact sensing



Low power consumption

7.1 Operating the AS5013

Typical Application.

The AS5013 requires only a few external components in order to operate immediately when connected to the host microcontroller.

Only 4 wires are needed for a simple application using a single power supply: two wires for power and two wires for the I²C communication. A

fifth connection can be added in order to send an interrupt to the host CPU when the magnet is moving away from the center and to inform that

a new valid coordinate can be read.
