W phase hall element input
Ground
Prevents to oscillate by lowering frequency characteristic of input/output gain with
capacitor connection between FC and Ground terminals
Start/stop control signal input “H”: start , “L”: stop
Not used
Operation mode switching input
Input/output gain switching input
Decides motor control stop voltage input (+2.1V)
Speed control signal input
Connected to gain setting resistor of first stage amp
+5V power supply
Ground of output transistor. Resistor insertion between RF and ground terminals realizes
to defect output current as voltage value, so over current to defect output current as
voltage value, so over current protection is posibble
Not used
W phase signal output
Ground
Ground
V phase signal output
U phase signal output
Not used
+12V power supply
When RF terminal is equal to CL voltage, current limmiter works
Hall FG signal output
Hall element power supply terminal
U phase hall element input
