TDA5141 Brushless DC motor drive circuit

TDA5141 The TDA5141 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. It is ideally suited for applications requiring powerful output sta.

TDA5141 Features

* Full-wave commutation (using push/pull drivers at the output stages) without position sensors

* Built-in start-up circuitry

* Three push-pull outputs:

* output current 1.9 A (typ.)

* low saturation voltage

* built-in current limiter

* Thermal
