Product specification
Brushless DC motor drive circuit
TDA5145
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.)
– built-in current limiter
– soft-switching outputs for low Electromagnetic
Interference (EMI)
Thermal protection
Flyback diodes
Tacho output without extra sensor
Motor brake facility
Direction control input
Reset function
Transconductance amplifier for an external control
transistor.
APPLICATIONS
General purpose spindle driver e.g.:
– Hard disk drive
– Tape drive
– Optical disk drive.
GENERAL DESCRIPTION
The TDA5145 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.
It includes bidirectional control, brake function and has a
special circuit built-in to reduce the EMI (soft switching
output stages).
QUICK REFERENCE DATA
Measured over full voltage and temperature range.
