GENERAL DESCRIPTION
The TDA5240T 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 VCR scanner motors.

FEATURES
• Full-wave commutation (using push/pull drivers at the output stages) without position sensors
• Built-in start-up circuit
• Optimum commutation independent on motor type or motor loading
• Built-in flyback diodes
• Three push-pull outputs:
   - 0.85 A output current
   - built-in current limiter
• Thermal protection
• Soft slope outputs for low radiation.
• Low current consumption by adaptative base-drive
• Tacho output without extra sensor.
• Comparator for external position generator (PG) signal
• Built-in multiplexer combining internal FG and external PG signal on one pin for easy use with a controlling microprocessor
• Linear control of the output stages
• PG signal output.

APPLICATIONS
• General purpose spindle driver ( e.g. VCR scanner motor).
