Microchip’s LX34070 inductive place sensor goals to switch much less correct magnet-based designs for safety-critical EV motor positioning management. The IC offers differential outputs, quick pattern charges, and options that make it functional-safety-ready for ISO 26262 compliance within the Automotive Security Integrity Stage-C (ASIL-C) classification.
The LX34070 inductive sensor affords quite a few benefits in comparison with magnetic resolvers and LVDTs, at a fraction of the fee. As a result of it makes use of PCB traces somewhat than transformer-based magnetic windings and coil buildings, the LX34070 has negligible dimension and mass in comparison with options that weigh as a lot as a pound. Accuracy is improved for the reason that LX34070 doesn’t depend upon magnet power, and the gadget enhances robustness by actively rejecting stray magnetic fields.
Together with two unbiased analog channels with demodulation, the LX34070 offers a built-in oscillator for driving the first coil. It additionally options differential output buffers with common-mode degree and safety circuitry towards output shorts, whereas automated acquire management maximizes decision over massive goal air hole ranges.
The LX34070 is available in a 14-pin TSSOP with AEC-Q100 certification to grade 0. It operates over a temperature vary of -40°C to +150°C, making it appropriate for a variety of economic, industrial, medical, and automotive sensor functions.
