Brushless DC motor drive circuit

GENERAL DESCRIPTION\nThe TDA5142T is a bipolar integrated circuit used to drive 3-phase brushless DC motors in full-wave mode. The device is sensorless (saving of 3 hall-sensors) using the back-EMF sensing technique to sense the rotor position. It includes a brake function and 6 pre-drivers able to • 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;
