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.
