Application Information
1. Chip Enable
This function turns on or off all blocks by low or high signal (active low).
2. U, V And W Phase Output Amp
These ampilifiers drive three phase outputs - U, V, and W which have 120 degree phase differences with each other. The three
phase waveforms are made with the two hall sensor signals by synthesizing the third phase signal.
3. Speed Control Part
This function compares the real motor rotation frequency with the 300 or 360Hz pulse divided from 1MHz clock pulse for
removing speed error when the motor is ’on’ and speed error is detected by PLL. The speed error is sent to the charge pump,
which repeats charging and discharging according to the error level. The charge pump output controls the output current to
keep the rotational speed stable.
4. Sensorless Index Signal Generation
FAN8422G can make index signals without an index hall sensor by special rotor magnetization.
