Microchip expects its LX34070 IC to help accelerate the global move away from expensive and less accurate magnet-based solutions for safety-critical EV motor position monitoring
CHANDLER, Ariz., June 15, 2022 (GLOBE NEWSWIRE) -- Developers of motor control systems are rapidly replacing Hall Effect position sensors and older magnetic resolver solutions with inductive alternatives that eliminate expensive magnets and other heavy transformer-based structures so they can be integrated onto simple, compact printed circuit boards (PCBs). Extending the world’s broadest line of inductive position sensors into the EV motor control market, Microchip Technology Inc. (Nasdaq: MCHP) announces the LX34070 IC that has been purpose-built for EV motor control applications. It includes differential outputs, fast sample rates and features that make it functional-safety-ready for ISO 26262 compliance in the Automotive Safety Integrity Level–C (ASIL–C) classification.
“The LX34070 inductive position sensor enables lighter, smaller, more reliable motor control solutions that meet stringent safety requirements, reduce overall system costs, and can operate seamlessly and precisely in the noisy environment of an automobile’s DC motors, high currents and solenoids,” said Fanie Duvenhage, vice president of Microchip’s mixed signal and linear analog business unit. “Designers can use the LX34070 to further streamline EV motor control designs by pairing it with other functional-safety-ready Microchip devices including our 8-bit AVR® and PIC® microcontrollers, our 32-bit microcontrollers, and our dsPIC® digital signal controllers.”
The LX34070 inductive position sensor solution offers numerous advantages compared to magnetic resolvers and Linear Voltage Differential Transducers (LVDTs), at a fraction of the cost. By using PCB traces rather than transformer-based magnetic windings and coil structures, the LX34070 device has negligible size and mass compared to alternatives that weigh as much as a pound. Accuracy is improved since the LX34070 does not depend on magnet strength, and the device improves robustness by actively rejecting stray magnetic fields. These and other features give designers greater flexibility over where they can place the thin, lightweight PCB-based LX34070 solution in their EV motor control designs.
PCB-based inductive position sensors use a primary coil to generate an AC magnetic field that couples with two secondary coils. A small metal target object disturbs the magnetic field so that each secondary coil receives a different voltage whose ratio is used to calculate absolute position. Using these techniques, Microchip introduced its first high-volume inductive sensor for automotive and industrial applications over a decade ago and has many programs in volume production. The LX34070 now brings the same proven PCB materials, approaches and simplified, low-cost packaging to EV motor control and other applications that need its high-speed and low-latency benefits.

Supporting Designers Through ISO 26262 Certification
Microchip works closely with automotive OEMs and suppliers to support their ISO 26262 compliance needs. The company’s functional safety packages give them what they need at various stages of the evaluation and design cycle, including certified safety manuals, Failure Mode Effect and Diagnostics Analysis (FMEDA) reports and, in some cases, diagnostic software such as certified self-test libraries for relevant ASILs. The company also practices customer-driven obsolescence, with Microchip continuing to supply devices as long as there is demand and all components are available, removing the risk of a forced redesign because a part may unexpectedly enter end-of-life (EOL).

Investors are trying to make sense of the markets, in face of conflicting signals. Year-to-date, we’re facing deep losses – but more recently, a sharp rally despite this week’s confirmation that we’re in a recession. Government data released on Thursday showed a 0.9% GDP contraction in Q2, which came on the heels of a 1.6% contraction in Q1. That’s two quarters in a row, the definition of a recession. Jim Cramer, the well-known host of CNBC’s ‘Mad Money’ program, reminds us the ‘conventional wis

The stock market is down so far this year; despite a rally since mid-June, the S&P is still down 15% year-to-date and the NASDAQ is down 23%. Share price drops like these get investors thinking about portfolio defense, and that naturally brings them around to dividend stocks. Companies can pay out dividends annually, quarterly, or monthly. Quarterly payments are the most common, but for truly defensive investors, monthly payments offer some advantages. Chief among those is the rapid and regular
A key gauge of U.S. inflation rose a sharp 1% in June, led by higher fuel prices, in a sign that price pressures in the economy are still intense and unlikely to relent quickly.
After dropping for the first 5 ½ months of the year, the S&P 500 has rebounded 8.5% since June 15 and 4.7% since July 26, the day before the Federal Reserve raised interest rates. Investors have turned enthusiastic toward stocks partly because Fed Chairman Jerome Powell said after the rate hike that the central bank will eventually slow its rate hike campaign. Never mind that the Fed said in its statement announcing the rate increase that it "anticipates that ongoing increases in the target range [for the federal funds rate] will be appropriate."
We wrote a story on Intel on June 8 with a headline of " Intel is Putting Its Negative News Behind It," and concluded that, "I learned early in my career to pay attention when a stock or commodity did not go lower on bearish news -- this was a sign that the news was already discounted. This is how I view the price action on INTC today. Traders could wait a couple of days but I do not expect INTC to make a new low close for the move down.
