IN1+, IN1-
IN2+, IN2-
IN3+, IN3-
Hall input for OUT1.
Hall input for OUT2.
Hall input for OUT3.
8
OUT1
Output 1.
9
OUT2
Output 2.
10
OUT3
Output 3.
3
VCC
Power supply for all blocks other than the output block.
14
VM
Used both as the power supply for the output block as well as for output current detection. The output current can
be converted to a voltage and detected by inserting the resistor Rf between this pin and VCC.
22
GND1
Ground for all blocks other than the output block.
11
GND2
Output block ground.
7
CR
PWM oscillator frequency determination.
25
INTIN
Integrator input.
26
INTOUT
Integrator output (speed control).
24
DOUT
Speed discriminator output.
Over speed
→ high
27
POUT
PLL output.
23
LD
Lock detector.
This pin goes low when the motor speed is within the lock range (
±6.25%).
4
5
FGIN+
FGIN-
FG pulse input (4V power supply).
FG pulse input.
6
FGOUT
FG amplifier output.
28
FGSOUT
FG amplifier output (after the Schmitt trigger circuit).
21
X’tal
Crystal oscillator connection. Connect a crystal oscillator element to this pin.
1
5V
5V power supply.
2
7V
7V power supply.
13
S/S
Start/stop control.
Low : start, high : stop
12
F/R
