Product specification
Brushless DC motor drive circuit
TDA5144
FEATURES
Full-wave commutation (using push/pull drivers at the
output stages) without position sensors
Built-in start-up circuitry
Three push-pull outputs:
– output current 2.0 A (typ.)
– low saturation voltage
– built-in current limiter
– soft-switching outputs for low Electromagnetic
Interference (EMI)
Thermal protection
Flyback diodes
Tacho output without extra sensor
Transconductance amplifier for an external control
transistor.
APPLICATIONS
General purpose spindle driver (e.g. for hard disk)
Laser beam printer.
GENERAL DESCRIPTION
The TDA5144 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.
A special circuit is built-in to reduce the EMI (soft switching
output stages). It is ideally suited as a drive circuit for hard
disk drive spindle motor requiring powerful output stages
(current limit of 2.0 A). It can also be used in e.g. laser
beam printer and other applications.
