Application Information
1. Output Block
3 Phase power transistor and free wheeling diodes
Reverse active type upper side diodes and parasitic lower side diodes
full wave current linear drive with current feedback
Connection with external capacitor to prevent voltage spike and oscillation by current drive
Output transistor commutation by "Winner takes all" method
Built in over current limit (OCL) circuit
2. Hall AMP Block
Detection of rotor position using 3 phase hall sensors
Determination of output commutation by hall signal
3. AGC Block
This block is remained output amplitude.
It is controlled by envelope through hall signals.
NOTES:
V
AGC
is voltage of AGC output.
H
NI
is hall non inverting input voltage.
H
I
is hall inverting voltage.
4. Speed Control Block
Digital phase locked loop (PLL) circuit
Generating error pulse between rising edge of clock and falling edge of FG signal.
High precision stable speed control
