Brushless DC motor drive circuit

GENERAL DESCRIPTION\nThe TDF5242T is a bipolar integrated circuit for driving 3-phase brushless DC motors in full-wave mode. The device functions sensorless, thus saving 3 hall-effect sensors, using the back-EMF (Electro Motive Force) sensing technique to sense the rotor position. It includes 6 pre- • Full-wave commutation without position sensors\n• Built-in start-up circuitry\n• Six outputs that can drive three external transistor pairs:\n   – output current 0.2 A (typ.)\n   – low saturation voltage\n   – built-in current limiter\n• Thermal protection\n• Tacho output without extra sensor\n• T;
