Overview
A5932 Three-Phase Sinusoidal Sensorless Fan Controller FEATURES AND BENEFITS • Automotive grade, AEC-Q100 qualified • Sinusoidal drive for low vibration and noise • Configurable closed loop speed curves • RD output • Quiet startup • Proprietary high-efficiency control algorithm • Automatic phase advance • Windmill detection • Fault output • FG speed output • Lock detection • Overcurrent limit (OCL) • Short-circuit protection (OCP) • Direction input • Brake input • Adjustable gate drive PACKAGES: Not to scale DESCRIPTION The A5932 three-phase motor controller incorporates sinusoidal drive to minimize audible noise and vibration for high-power fans.
A sinusoidal voltage profile is applied to the windings of the motor at startup to quietly start up and gradually ramp up the motor to desired speed.
The motor speed is controlled by applying a duty cycle command to the speed (SPD) input.
The SPD input is allowed to operate over a wide frequency range.
The A5932 is available in a 24-contact 4 mm × 4 mm QFN with exposed thermal pad (suffix ES), a 24-contact 4 mm × 4 mm QFN with exposed thermal pad and wettable flank (suffix ES, -J option), and a 24-lead TSSOP with exposed thermal pad (suffix LP).
These packages are lead (Pb) free, with 100% matte-tin leadframe plating.
