The 18SCT005, a high-voltage monitor capable of 1200V at 0.7% accuracy

As EV battery voltages continue climbing to 800V, 1,000V, and beyond, the sensing function tasked with monitoring that voltage must scale alongside it, without inheriting the drift, bulk, and complexity of discrete resistors. The 18SCT005 demonstrates that high-voltage sensing can be condensed into a single, low-cost IC without compromising accuracy, temperature stability, or transient response. As OEMs and Tier 1 suppliers design the next generation of battery management systems, inverters, and onboard chargers, a monolithic approach like this offers a simple path to a smaller, more reliable, and easier-to-validate high-voltage measurement chain, exactly the kind of building block to support the next wave of EV platforms.

High-voltage systems are central to modern engineering across electric mobility, industrial power electronics, and medical equipment. These systems rely on accurate voltage measurement to operate within safe limits, maintain efficiency, and respond to changing conditions. High-voltage values feed directly into control loops, protection logic, and diagnostic routines. Any deviation between actual and measured voltage introduces uncertainty that propagates through the system.
Scaling high-voltage down to a measurable range appears straightforward at first glance. In practice, this task involves maintaining an accurate ratio with voltage, preserving stability across temperature, and ensuring that measurement remains reliable over time. These requirements place high-voltage sensing in a different category than for low-voltage measurement. The constraints are tighter, the consequences of error are more serious, and the design trade-offs are more complex.

Physics studies nature in general. The fundamental basis of physics is based on repeatable observations, which leads to knowledge being built. In semiconductor manufacturing, this translates into a deep understanding of the “related” parameters in addition to the main goal of a specific operation. Creating an IC is a sequential process where hundreds to a few thousand steps are used in sequence from concept/design/verification/manufacturing/tests/packaging to achieve something that works most of the time. This sequential process is a web of interactions that are dictated by first principles. Understanding the relevance of these interactions helps guide the team to the best possible outcome.

How SimpleChips designs high-voltage silicon for systems that must perform reliably over decades
Samir Jaber, Wevolver.com, January 2026
Much of semiconductor innovation is measured by what a device can do at its limits. SimpleChips measures innovation by what a system can be trusted to do over time.
With high-voltage, electronics problems surface slowly through drift, nonlinearity, thermal behavior, or edge conditions that only appear after years in the field. In critical systems, from electrified powertrains to medical devices, these effects often outweigh peak performance. They determine whether a system remains predictable, serviceable, and safe long after it has been deployed.

A test chip (named Yieldchip) was designed, simulated, fabricated, and tested on a 3- mu m process. The layout of the Yieldchip’s cells enables the test program to electrically locate and identify active faults, thereby automating the, classification of defects. The Yieldchip can detect more than one defect per circuit in most circumstances. The algorithm can identify the 21 simple defects of the cells and can be used as an expert system to extend this list. Unidentified detectable faults are flagged at all times and located if possible.

The addition of a ramped nucleation cycle, just after an initial oxidation, is shown to greatly increase the precipitation of interstitial oxygen during simulated processing on N/N+ antimony doped epitaxial wafers. When used with fully processed wafers, the ramped nucleation improves internal gettering. Oxygen precipitate density and bulk stacking fault density achieved are about a factor of 100 higher when using ramped nucleation. These results indicate that N/N+ antimony doped epitaxial wafers have an intrinsic gettering capability as good as that of lightly doped material when using an activation cycle (initial oxidation) and subsequent ramped nucleation. A method for calculating bulk stacking fault density is presented. It is shown that, at high concentration (above 107 cm−3), the square of the bulk stacking fault length is inversely proportional to their density. This finding indicates that the growth of bulk stacking faults is limited by the supply of interstitial silicon generated in the bulk during oxygen precipitate growth.
