9 / 14 page LB11850VA No.A0609-9/14 3) Additional description of operations The LB11850 forms a feedback loop inside the IC so that the FG period (motor speed) corresponding to the control voltage is established by inputting the duty pulse. The operation inside the IC is as follows. Pulse signals are created from the edges of the FG signals as shown in the figure below, and a waveform with a pulse width which is determined by the CR time constants and which uses these edges as a reference is generated by a one-shot multivibrator. These pulse waveforms are integrated and the duty ratio of the pre-driver output is controlled as a control voltage. Furthermore, by changing the pulse width as determined by the CR time constant, the VCTL versus speed slope can be changed as shown in the speed control diagram of the previous section. However, since the pulses used are determined by the CR time constant, the variations in CR are output as-is as the speed control error.
