Transmission systems have made tremendous advances in the last decade with respect to efficiency improvements with the adoption of designs such as continually-variable transmissions (CVT) and double-clutch transmissions (DCT); and the advancements made in higher gear linear automatic transmissions. The automotive industry’s continual push for fuel-consumption and carbon dioxide emissions reductions has presented a number of technical challenges for the sensing systems required to support these platforms. Allegro’s sensors have led the way in the market for these technologies:
Allegro is also a leading supplier of both brush and brushless motor drive technology which can be used in the design of electronic clutches, shifters, and gear selectors. Allegro is a leader in the field of controlling BLDC motors and has products ranging from simple direct-drive I/O up to and including fully automotive-grade sensorless BLDC control ICs.
Allegro also offers single- and multiple-output DC/DC regulators for powering Transmission Control Units (TCU). Devices are full Automotive Grade designed and qualified and offer significant fault protection for robust system solutions.
