With mobile devices such as smartphones and laptops using different charging interfaces and standards, users often need multiple chargers for their various devices. To address this issue, the USB Implementers Forum (USB-IF) has been actively promoting the USB Power Delivery (USB PD) standard. Today, USB PD is ubiquitous across smartphones, digital cameras, laptops, and monitors, allowing a single cable to handle charging, data transfer, and video output simultaneously.

Chroma has launched a highly integrated testing solution that supports the latest USB Power Delivery 3.2 specification: the Chroma A223810 USB-C Signal Module paired with the A223808 Power Module. This combination supports up to 140W (28V/5A) power output and features a Power Role Status Monitor, fully accommodating the various power roles (Source/Sink/DRP) required for PD compliance testing.

Next-Gen USB-C PD 3.2 Solution Streamlines Testing Workflows

As the USB Power Delivery standard continues to evolve, Chromaˈs latest PD 3.2-compliant A223810 USB-C Signal Module (paired with A223808 Power Module) supports power specifications up to 140W (28V/5A) and offers a programmable voltage range of 3–28V (1mV/step). It supports SPR (Standard Power Range), EPR (Extended Power Range), USB 3.2 Gen2, AVS (Adjustable Voltage Supply, 100mV/step), and PPS (Programmable Power Supply, 20mV/step) for a comprehensive suite of testing applications.

This solution features both DC power output and load simulation capabilities, enabling validation of video, power, communication, and power role auto-switching. The built-in USB-C Program automates a complex bundle of tasks, including DP Alt Mode video output, VBUS voltage/current testing, USB data rate and version verification, and automatic cable orientation switching (Cable Flip). Upon completion, Pass/Fail results are displayed instantly on-screen. 

USB-C VBUS OCP testing accurately simulates over-current protection performance.

A critical component of USB-C safety is Over-Current Protection (OCP). When paired with the A223808 Power Module, the A223810 USB-C Signal Module enables accurate simulation of over-current conditions on the power sink side (with a current value adjustable between 5A and 10A) to verify the protection triggers of the USB-C source.
With the newly designed single-page UI, users can simultaneously view module status, configure test functions, access graphical representations of the device under test, use test shortcuts, and monitor test programs and results in real time. This intuitive layout streamlines both the setup and the execution process, significantly reducing overall testing time.
