Additional preview pages of the TDA5143T datasheet.

The TDA5143T 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.

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 0.85 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 a.
