Hello,

CY4500 is avaliable to measure current or voltage of USB 3.0 Device which not applyed USB PD controller??

Hi,

The main function of CY4500 is to catch and decode PD message. The voltage and current measurement has a low accuracy. If you got two Type-C to USB converter, it can be done. But I do not recommend it.

Hi,

Although I measure voltage and current of my product using USB C-type cable(both host and device), do you not recommend it?

It means that I don't use USB converter.

Hi,

The typical accuracy of the VBUS current displayed is +/- 0.15 A and the VBUS voltage displayed is +/- 1%. You can evaluate whether it meet your demand.
