APPLICATION INFORMATION
1. CHIP ENABLE
This function turns on or off all blocks by low or high signal.
2. U, V AND W PHASE OUTPUT AMP
This part drives the output as making U, V and W current waveform having 120
°
C phase difference with using the
current ratio of each amp output after giving the signal occurred by 2 hall sensors to U amp and V amp.
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 motor is on and speed error is detected by PLL.
The speed error sent to charge pump part which repeats charge and discharge controls the output current of the
output amp to keep a stable rotation.
