Download the PDF of this issue, with ideas on how to resolve optical encoder outputs with a PSoC GPIO and interrupts, and how to enhance short-circuit protection with a high-side load driver.

This article is part of the Ideas for Design Series: Volume 3

The Volume 3, No. 8 issue of Ideas for Design features:

  • A way to use the GPIO port of a Cypress PSoC IC (plus software) to resolve and decode quadrature signals from a standard rotary optical encoder, and thus determine motor rotor position and direction. 
  • A simple circuit that adds short-circuit load protection to a basic driver, such as the output of a simple logic gate, while allowing it to control a high-power load operating at a much-higher voltage without fear of destructive short-circuit conditions.
