TDA5143T - Brushless DC motor drive circuit
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-in to reduce the EMI (soft switching output stage

* Built-in start-up circuitry
* Three push-pull outputs:
* output current 0.85 A (typ.)
* low saturation voltage
* built-in current limiter
* soft-s
