TDA5140A

The TDA5140A 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.

FUNCTIONAL DESCRIPTION

The TDA5140A offers a sensorless three phase motor

drive function. It is unique in its combination of sensorless

motor drive and full-wave drive. The TDA5140A offers

protected outputs capable of handling high currents and

can be used with star or delta connected motors. It can

easily be adapted for different motors and applications.

The TDA5140A offers the following features:

•

Sensorless commutation by using the motor EMF.

•

Built-in start-up circuit.

•

Optimum commutation, independent of motor type or

motor loading.

•

Built-in flyback diodes.

•

Three phase full-wave drive.

•

High output current (0.8 A).

•

Outputs protected by current limiting and thermal

protection of each output transistor.

•

Low current consumption by adaptive base-drive.

•

Accurate frequency generator (FG) by using the

motor EMF.

•

Amplifier for external position generator (PG) signal.
