FUNCTIONAL DESCRIPTION
The TDA5141 offers a sensorless three phase motor drive function. It is unique in its combination of sensorless motor
drive and full-wave drive. The TDA5141 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 TDA5141 offers the
following features:

SYMBOL
stg
amb
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 (1.9 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.
