Equivalent circuit
Pin function
3VS
≤ VCC2
Power supply input that determines the output
amplitude. It must be set to a voltage equal or
lower than VCC2.
4VCC24 to 10 V
Power supply for power amplifier systems other
than motor drive transistors. Power supply pin
that provides voltage for blocks other than control
blocks supplied by VCC1.
5VCC14 to 6 V
Power supply that provides voltage for the Hall
amplifier, the forward/reverse circuit, the FG
amplifier, and the thermal shutdown circuit.
7
ANGLE
Connect a resistor between this pin and GND.
Changing the value of this resistor will change the
Hall input-output gain (motor waveform slope).
9FGIN–
0 V min
FG signal input pin
10
FGIN+
3.5 V max
(When VCC1 is 5 V)
11
FGOUT1
FG amplifier output pin
6
ST. BY
(H): 2.0 V max
All circuits can be made inoperative either by
(L): 0.8 V min
connecting this pin to GND, or by leaving it open.
(When VCC1 is 5 V)
In that state the supply current will be
approximately 0 A. Hold at 2 V or higher during
normal operation.
