TDA5143T circuit equivalent, brushless dc motor drive circuit.
* Full-wave commutation (using push/pull drivers at the output stages) without position sensors
* Built-in start-up circuitry
* Three push-pull outputs:
&.
TDA5143T
* General purpose spindle driver (e.g. for hard disk)
* Laser beam printer. GENERAL DESCRIPTION The T.
The TDA5143T 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. A special circuit is built.
