Brushless DC motor drive circuit
TDA5145
Fig.2 Pin configuration.
FUNCTIONAL DESCRIPTION
The TDA5145 offers a sensorless three phase motor drive
function. It is unique in its combination of sensorless motor
drive and full-wave drive. The TDA5145 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
TDA5145 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 (2.0 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 EMF.
Direction of rotation controlled by one pin.
Uncommitted operational transconductance amplifier
(OTA), with a high output current, for use as a control
amplifier.
Brake function.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
