Advantest Unveils Innovative Power Multiplexer for Testing

Advantest Revolutionizes Testing with New Power Multiplexer

Advantest Corporation, a leader in semiconductor test equipment, has recently introduced an advanced power multiplexer designed for the V93000 EXA Scale test platform. This innovative device, known as the PMUX02 Power MUX, is set to transform multi-site testing processes for a variety of power and analog devices. This includes essential technologies found in battery management systems (BMS), automotive components, and power management integrated circuits (ICs), showcasing a significant evolution in the capabilities of semiconductor testing.

Remarkable Advancements in Power Multiplexing

The PMUX02 Power MUX stands out with its enhanced switch density, featuring 22 switches, nearly doubling the capacity of previous models. This increase allows for a greater range of testing scenarios, accommodating an extended voltage range of ±160 volts (V). These features come together to offer a streamlined approach, reducing overall testing costs, particularly for devices with higher pin counts and mixed-signal configurations.

Understanding the Role of Power Multiplexers

At its core, a power multiplexer is essential for switching between different power sources and measurement instruments. This functionality is particularly critical for devices under test (DUTs), especially as electric vehicles (EVs) become more sophisticated. With an increasing number of battery cells stacked in configurations like 24+ cells, the need for robust BMS capable of managing 150V or more becomes paramount. As automotive ICs escalate in complexity, testing demands also rise, requiring more parallel sites and advanced multiplexing solutions.

The Competitive Edge of PMUX02

Ralf Stoffels, the general manager and executive vice president of Advantest's V93000 Product Unit, emphasized the benefits of the PMUX02 in optimizing loadboard density. He noted, "With the ability to integrate additional switches, customers can significantly enhance the capacity of their testing setups without incurring the costs associated with purchasing additional instrument cards." This innovation empowers customers to maximize their resources while improving test efficiency.

Seamless Integration and Future Availability

The PMUX02 is designed for compatibility with existing systems, particularly the earlier PMUX01 model. Customers can effortlessly switch to the new multiplexer without the need for new loadboards. Additionally, it is fully integrated into Advantest’s SmarTest 8 control software, which employs advanced routing tools essential for agile development in application testing.

Adoption and Availability of PMUX02

Several customers have already begun leveraging the advantages offered by the PMUX02 for their projects, underlining its relevance to today’s semiconductor testing landscape. Anticipated availability on a global scale is projected for early 2025, highlighting Advantest's commitment to addressing the ever-evolving demands of the semiconductor industry.
