NXP Semiconductors TDF5242T
The 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-drivers able to control external FETs (Field Effect Transistors) or bipolar transistors.| Part No. | TDF5242T |
