A4942 Three-Phase Sensorless Fan Driver IC

Allegro MicroSystems A4942 Three-Phase Sensorless Fan Driver IC incorporates BEMF sensing to eliminate the requirement for Hall sensors in fan applications. An integrated closed-loop speed control system allows the accurate setting of maximum/minimum speeds via the selection of external resistors. The duty cycle demand applied to the PWM input controls the speed, and the PWM input operates over a wide frequency range. Integrated current limiting with adjustable soft start minimizes the power supply load while the fan speeds up. The Allegro MicroSystems A4942 IC is supplied in a 20-contact 4mm x 4mm QFN package (suffix ES) with an exposed pad for enhanced thermal dissipation.

Magnetic Speed Sensor ICs

Allegro MicroSystems Magnetic Speed Sensor ICs offer a comprehensive portfolio covering the full range of speed and speed with direction sensor ICs. These products include a two- and three-wire interface, a magnetic encoder (ring magnet) and gear tooth sensing, Hall and GMR technology, and ASIL-compliant options for transmission, wheel speed, engine, e-motors, and many more encoder and gear tooth sensing applications.
