Speed lock detection output pin.
This is an open collector output.
Goes low when the motor speed is within the speed
lock range(±6.25%)
FG amplifier output pin.
This pin is connected to the FG Schmitt comparator
circuit internally in the IC.
FG amplifier inverting input pin.
FG amplifier non-inverting input pin.
1/2 VREG potential.
Connect a capacitor between this pin and GND.
Hall input pins.
The input is seen as a high level input when IN + >
IN - , and as a low level input for the opposite state.
If noise on the Hall signals is a problem, insert
capacitors between the corresponding IN + and IN -
inputs.
Output current detection reference pin.
Connect to GND side of the current detection
resistor Rf.
