... Therefore, a start oscillator is provided that will generate commutation pulses when no zero-crossings in the motor voltage are available. A timing function is incorporated into the device for internal timing and for timing of the reverse rotation detection. 9 Product specification TDA5145TS ( 220 nF nF ...

... For the watchdog function a value for CAP-TI is recommended. To ensure a good start-up and commutation, care must be taken that no oscillations occur at the trailing edge of the flyback pulse. Snubber networks at the outputs should be critically damped. Typical voltage waveforms are illustrated in Fig.9. 12 Product specification TDA5145TS ...

... If the chosen value of CAP-TI is too small oscillations can occur in certain positions of a blocked rotor. If the chosen value is too large, then it is possible that the motor may run in the reverse direction (synchronously with little torque). Fig.9 Typical CAP-TI and V Other design aspects There are other design aspects concerning the application of the TDA5145TS besides the commutation function. They are: Direction function Brake function Reliability. ...
