TDA5141 Datasheet (NXP) - Brushless DC motor drive circuit

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
