SPI communication

No direct inputs

The eXtreme Switch can do PWM without a PWM timer module in the MCU.


eXtreme Switches configuration for self PWM control

With a single SPI message we can control ON/OFF and

setup PWM duty Cycle

Watchdog is automatically refreshed with any SPI message

We change PWM duty Cycle up and down smoothly.
