GENERAL DESCRIPTION
The TDA5146T is a bipolar integrated circuit used to drive brushless DC motors in full–wave mode. The device senses the rotor position using an EMF –sensing technique and is ideally suited as a drive circuit for a hard disk drive motor or tape drive.

FEATURES
• Full–wave commutation (using push/pull drivers at the output stages) without position sensors
• Built–in start–up circuit
• Three push–pull outputs:
    – 2 A output current (Typical)
    – Built–in current limiter
• Thermal protection
• Soft switching outputs
• Flyback diodes
• Tacho output sensor
• Brake function
• Direction control input
• Reset function
• FET driver stage to be used in a buck converter

APPLICATIONS
    General purpose spindle driver (e.g., HDD, tape driver)
