The Chip That Wouldn't Die: Why Your Multimeter Still Uses Old-School Nexperia Logic (And Why You Should Care)

You pick up your multimeter to troubleshoot a USB-PD circuit that’s refusing to negotiate a charge profile. The device itself hasn’t been updated in five years. Inside, there’s a handful of discretes, a few logic gates, and an operational amplifier that was designed in the 1980s.

If you’re an engineer, you know the feeling. The 'critical path' of your design runs through chips so generic they’re almost invisible. And right now, a very specific one is making headlines: Nexperia.

Seriously, I’ve been digging into this for the last few weeks because a client’s power supply design got held up over a single MOSFET. It wasn’t about supply chain cost; it was about supply chain control.

So, Who is Nexperia, and Why Is a 'Dutch' Chipmaker Suddenly a Geopolitical Football?

Here’s the thing. If you look at a bill of materials (BOM) for any mid-range industrial device—your multimeter, a PLC, a charging station—you’ll find Nexperia parts. They are everywhere. They are the 'water' of the electronics industry: essential but assumed.

Nexperia was spun off from NXP (originally Philips) in 2017. They make the boring, high-volume, high-reliability stuff: diodes, transistors, standard logic (like the 74HC series), and power MOSFETs. They are the undisputed king of the 'small-signal' and 'discrete' semiconductor world.

The problem started when it was taken over by a Chinese-owned investment firm. This isn't just a 'Chinese chipmaker' story (which is a huge simplification and usually a red flag in reporting). It’s a story about a company that is physically located in Europe (HQ in Nijmegen, Netherlands, with fabs in Germany and Wales), making chips for global customers, but whose ultimate parent company is... well, let’s just say it’s complicated.

The surprise wasn't the technical challenge of their GaN (Gallium Nitride) chips. It was the political one. The Dutch government, under pressure from the US, has essentially 'handed back control' over the export of specific, high-end chipmaking equipment to the Dutch state, limiting what Nexperia can send to China. The core issue isn't *if* they can make a 1-V logic chip; it's *where* that knowledge and its associated equipment can go.

The Cost of Geopolitics on Your Multimeter Order

I have mixed feelings about this entirely. On one hand, this political interference feels like it’s designed to slow down the inevitable. On the other hand, if you’ve ever had a rush order delayed because a critical standard logic chip from a 'Chinese' source was red-flagged by customs, you know the cost is real.

Let’s be real: that delay cost you time. If you're waiting on a batch of logic gates to finish a prototype board—never mind a full production run—a two-week delay can kill a project. I saw this happen earlier this year. A client needed fifty pieces of a specialized Nexperia logic chip for an earthquake monitoring station. The order was placed. The vendor went dark. Turns out the 'stock' was sitting in a bonded warehouse while the export license was being reviewed.

We paid $1,200 extra in rush fees to get a similar chip from a different manufacturer (TI, in this case) air-shipped from a different distribution hub. The client's alternative was losing a $50,000 contract clause. That’s the cost of a 'hands-off' approach to your BOM.

GaN: The Multimeter’s Unlikely Future

Most people look at a multimeter and think 'analog display.' But the modern multimeter is a digital power management computer. And the next big leap isn’t speed; it’s power density.

Nexperia is betting big on GaN (Gallium Nitride) for their power MOSFETs. This isn't about your phone charger. For a multimeter or a USB-PD circuit, GaN allows for a way smaller power stage. Imagine a multimeter that doesn't need a giant transformer to handle 600V measurements because the switching transistor is 1/4th the size and runs cooler. That’s GaN.

Nexperia’s GaN FETs (specifically the CCPA series for automotive, or the GAN063-650WSA for industrial) are game changers for this reason: they are designed to be drop-in replacements for silicon MOSFETs in many cases. No new driver design is needed.

But here’s the hidden cost. While the chip itself is a drop-in, the supply chain is not. If you're designing a product that uses a Nexperia GaN FET, you’re now tying your project to the stability of a company whose supply of raw materials (epitaxial wafers) and manufacturing capacity might be subject to sudden political shifts. The cheapest chip on the BOM could be the most expensive risk.

So, How Do You Reset a Phone (Or, More Practically, Your Supply Chain Strategy)?

You don’t reset a phone by pulling the battery anymore. But you do 'reset' your sourcing strategy by asking one critical question: What else is on the BOM that I’m ignoring?

When you’re juggling the USB-PD negotiation stack and simultaneously trying to record a list of current measurements, you can forget that the 74LVC1G07 buffer is from a company that’s currently a political hot potato.

I’ve learned to ask: 'What's my Nexperia exposure?'
Then I look for a cross-reference. Not because Nexperia makes bad parts—they make some of the best. But because the certainty of delivery is now more valuable than the price of the part.

For critical functions (like the main power switch in your multimeter), I specify a second source. For non-critical logic, I accept the risk.

Look, the reality is that the 'hand back control' of Nexperia is a signal. It tells you that the era of frictionless global trade for even boring little chips is over. The total cost of ownership for your next design isn't just component cost. It’s customs brokerage fees, it’s the cost of a one-week delay on a rush order, and it’s the headache of finding a replacement for a part that’s suddenly become a 'controlled good.'

The best time to figure out your Nexperia backup plan was six months ago. The second-best time is while you’re reading this.
