NXP Semiconductors 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), reset and park facilities and an accurate speed regulator.| Part No. | TDA5341 |
