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.

• Suitable for use with a wide tolerance, external PG

sensor.

• Built-in multiplexer that combines the internal FG and external PG signals on one pin for easy use with a controlling microprocessor.

• Uncommitted operational transconductance amplifier (OTA), with a high output current, for use as a control amplifier.
