Microchip expects its LX34070 IC to help accelerate the global move away from expensive and less accurate magnet-based solutions for safety-critical motor position monitoring.

Developers of engine control systems are rapidly replacing Hall position sensors and older magnetic resolver solutions with inductive alternatives that eliminate expensive magnets and other heavy-duty transformer-based structures so they can be integrated into simple, compact prints. PCBs. Expanding the world’s widest line of inductive sensors for the position of the electric motor control market, Microchip Technology Inc. (Nasdaq: MCHP) announces LX34070 IC which is specially designed for motor control applications. It includes differential outputs, fast sample rates and functions that make it ready for functional safety in accordance with ISO 26262 in the Level-C (ASIL-C) car safety classification.

“The LX34070 Inductive Position Sensor enables lighter, smaller and more reliable engine management solutions that meet stringent safety requirements, reduce overall system costs and can work seamlessly and accurately in noisy car environments. DC motors, high currents and solenoids, “said Fanny Duvenhage, vice president of microchip’s mixed-signal and linear analog business unit. “Designers can use the LX34070 to further streamline motor control designs by pairing it with other ready-to-use Microchip safety 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 over magnetic resolvers and differential voltage converters (LVDT) for a small fraction of the price. Using traces of printed circuit boards instead of transformer-based magnetic coils and coil structures, the LX34070 has a negligibly small size and weight compared to alternatives that weigh as much as a pound. Accuracy is improved, as the LX34070 does not depend on the strength of the magnet, and the device improves strength by actively rejecting scattered magnetic fields. These and other features give designers more flexibility on where to place the slim, lightweight PCB-based LX34070 solution in their electric motor control designs.
