8 Application Information
Benefits of AS5130
Application Example 1
The AS5130 requires the serial interface via SSI for the programming of the OTP register. This configuration is
recommended for applications, where the supply voltage for the AS5130 is shared among other parallel IC’s during
programming, such as a microcontroller.

VDD, VSS and the PWM output. The circle over the center of the chip represents the diametrically polarized magnet.
Additionally, the CAO pin will deliver an analog voltage indicating a missing magnetic field. This signal could be used to
drive an external LED or to detect an alert signal.
