Product specification
Brushless DC motor drive circuit
TDF5140A
FEATURES
Full-wave commutation (using push/pull drivers at the
output stages) without position sensors
Built-in start-up circuitry
Three push-pull outputs:
– 0.8 A output current (typ.)
– low saturation voltage
– built-in current limiter
Thermal protection
Flyback diodes
Tacho output without extra sensor
Position pulse stage for phase-locked-loop control
Transconductance amplifier for an external control
transistor.
APPLICATIONS
VCR
Laser beam printer
Fax machine
Blower
Automotive.
GENERAL DESCRIPTION
The TDF5140A is a bipolar integrated circuit used to drive
3-phase brushless DC motors in full-wave mode. The
device is sensorless (saving of 3 hall-sensors) using the
back-EMF sensing technique to sense the rotor position.
QUICK REFERENCE DATA
Measured over full voltage and temperature range
