PowerPSoC® – Measuring Channel Current Using the Analog Input Multiplexer (AINX)

Question: How to measure channel current using the Analog Input Multiplexer (AINX)?

 

Answer:

 

The PowerPSoC® controllers contain the analog input multiplexer (AINX) block which provides the capability to route the output of current sense amplifiers (CSA) to the analog blocks. The analog blocks can be configured as an ADC and used to measure the current through the channels.

The attached example project demonstrates how the current through any of the channels can be monitored using the AINX block, using the CY3268 PowerPSoC demonstration kit. For a detailed explanation of the projects and the instruction to use the same, refer the attached document.
