TDA5146T
FUNCTIONAL DESCRIPTION
The TDA5146T offers a sensorless three phase motor drive function. It is unique in its combination of sensorless motor drive and full–wave
drive.
The TDA5146T 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 TDA5146T 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 (1.8 A)
• Outputs protected by current limiting and thermal protection of each output transistor
• Low current consumption by adaptive base–drive
• Soft switching pulse output for low radiation.
• Accurate frequency generator (FG) by using the motor BMF
• Direction of rotation controlled by one pin.
• FET driver stage to be used in a buck converter
LIMITING VALUES
