Description

The TDF5242T is a bipolar integrated circuit for driving 3-phase brushless DC motors in full-wave mode.

The TDF5242T 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. It offers brake and direction control. It is ideally suited for high-power applications such as high-end hard disk drives and automotive applications.
