    ... 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. ...

    ... Possibilities of motor control Reliability. FG SIGNAL The FG signal is generated in the TDA5144 by using the zero-crossing of the motor EMF from the three motor windings. Every zero-crossing in a (star connected) motor winding is used to toggle the FG output signal. The FG frequency is therefore half the commutation frequency. All transitions indicate the detection of a zero-crossing ...

    ... It is possible, that when braking, the motor voltage (via the flyback diodes and the impedance on VMOT) may cause higher currents than allowed ( 0.6 A). These currents must be limited externally. June 1994 15 Product specification TDA5144 ...
