TDA5341 Brushless DC motor and VCM drive circuit with speed control

TDA5341 The TDA5341 is a BiCMOS integrated circuit used to drive brushless DC motors in full-wave mode. The device senses the rotor position using an EMF sensing technique and is ideally suited as a drive circuit for a hard disk drive motor. The TDA5341 also includes a Voice Coil Motor driver (VCM.
