Brushless DC motor drive circuit
TDA5142T
Fig.2 Pin configuration.
FUNCTIONAL DESCRIPTION
The TDA5142T offers a sensorless three phase motor
drive function. It is unique in its combination of sensorless
motor drive and full-wave drive. The TDA5142T offers
protected outputs capable of driving external power FETs
or bipolar power transistors. It can easily be adapted for
different motors and applications. The TDA5142T 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.
• Six output drivers.
• Maximum output current 0.25 A.
• Outputs protected by current limiting and thermal
protection.
• Low current consumption.
• Accurate frequency generator (FG) by using the
motor EMF.
• Brake function.
• Uncommitted operational transconductance amplifier
(OTA), with a high output current, for use as a control
amplifier or as a level shifter in a Switched Mode Power
Supply (SMPS) drive.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
