Engineering analysis and practical perspectives on semiconductor design, manufacturing and supply chains. We explore technologies, production considerations and industry developments to help teams make informed decisions, including when working in China.
Isolation ratings answer different questions. A table of what each rating is for and one dated datasheet reading, set against the different gate-drive needs of IGBT, SiC, superjunction MOSFET and GaN stages.

An electrostatic chuck supply is more than a kilovolt source. Clamp and release waveforms, low-current sensing, RF coexistence, fault handling, and the boundary between custom ICs and external high-voltage hardware shape the real architecture decision.

Piezo haptics, nanopositioning, ultrasonic cleaning, inkjet and medical ultrasound may all need high-voltage drive, but they require very different IC architectures. This practical map shows where each approach fits and where analog IC opportunities remain.
Piezo Driver ICs Are Not One Market Read More »
Solid-state transformers create real semiconductor demand, but not for one monolithic transformer chip. This evidence-led architecture map shows where SiC modules, isolated gate drivers, sensing, bias power, protection and control actually fit—and what must be proven before calling any function a custom-IC opportunity.

The planned Navitas–Magnachip SiC transfer highlights a broader rule: masks and recipes may move, but manufacturing behavior, models, reliability, test and route-release evidence must be re-established.

See where copper still wins, where fiber takes over, and how pluggable optics, LPO, CPO and optical I/O shift system responsibility.
At a 48/54 V AI-server input, protection must do more than limit inrush. Integrated eFuses and external-MOSFET hot-swap controllers make different tradeoffs in safe operating area, current scaling, thermal design, fault timing and telemetry. Here is how to compare them on equal terms.

The low-altitude economy extends far beyond passenger eVTOL. Industrial UAVs, cargo aircraft, docks, chargers, protected power distribution and diagnostic telemetry may create earlier opportunities for power-analog IC suppliers.
Beyond eVTOL: Where Power-Analog ICs Fit in the Low-Altitude Economy Read More »
At multi-kilovolt, hundreds-of-amp scale, device speed is only part of the contest. DC fault energy, always-on breaker losses, microsecond protection windows, hybrid architectures, packaging, and qualification increasingly decide which power-semiconductor systems are viable.
At HV/HC Scale, Protection — Not the Switch — Is Becoming the Battleground Read More »
