No one wants a loud laptop. Allegro offers the industry's first code-free FOC BLDC fan driver for extremely quiet, extremely efficient performance. See what else we have to offer for your modern computing devices.
Electronic devices allow inexpensive management of server components with minimal contributions to thermal signature, power draw, or physical size. Some, such as the Allegro MicroSystems A4942 three-phase sensorless BLDC fan-motor driver chip, are small enough to fit onto the hub PCB of mini ducted ...了解更多
Allegro MicroSystems uses the latest integrated circuit technology in combination with the century-old Hall effect to produce Hall-effect ICs. These are contactless, magnetically activated switches and sensor ICs with the potential to simplify and improve electrical and mechanical systems.了解更多
This application note will discuss the mechanism of CMR and focus on how to best use this mechanism through optimized circuit board design and layout for sensors that need an external magnetic core, sensors that have a core built into the package, and sensors that have an integrated ...了解更多
