The AH5792 smart motor controller from Diodes Inc. (Hauppauge, NY) integrates a Hall sensor and amplifier, complete digital circuitry, and a full bridge output driver in an SOT553 package. These features eliminate the need for external components such as a timing capacitor, and suit the controller for low-voltage micro motors and ultra-thin cooling fan applications.
Operating voltage is 1.8 to 5 V, and operating temperature range is -40 to +100°C. Features include locked rotor detection, self-restart, and frequency generator output.
