- About Allegro
The conventional powertrain is composed of an internal combustion engine paired with the transmission. This system has made tremendous advances in the last decade with respect to efficiency improvements and the advancement and adoption of technologies such as dual overhead camshaft (DOHC) engine configurations, variable valve timing (VVT) engines, stop/start engines, high gear ratio automatic transmissions, continually-variable transmissions (CVT), and double-clutch transmissions (DCT).
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 sensor ICs have led the way in the market for these technologies:
Allegro is 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. Learn more»
