Outputs
The PWM signal controls the duty from the low side transistor.
IN1+, IN1–
IN2+, IN2–
IN3+, IN3–
11, 12

6, 8
Hall inputs for the three phases
The logic H state means that V
IN
+ is greater than V
IN
–.
FG IN+
13
FG comparator noninverting input
FG IN–
14
FG comparator inverting input
GND1
15
Control system ground
GND2
16
Subsidiary ground.
PWM
17
Sets the PWM oscillator frequency. Insert a capacitor between this pin and ground.
FC
19
Current control circuit frequency characteristics correction. Insert a capacitor between this pin and ground.
PD
21
Phase comparator output. Outputs the phase error as changes in the pulse duty.
EI
22
Error amplifier input
EO
23
Error amplifier output
TOC
24
Torque command input. This pin is normally connected to the EO pin. When the TOC potential falls, the low side output
transistor on duty is changed and the torque increases.
FGFIL
25
FG filter connection. Insert a capacitor between this pin and ground if noise on the FG signal is a problem.
CSD
26
Sets the operating time for the rotor constraint protection circuit and the initial reset operation.
Insert a capacitor between this pin and ground. If the rotor constraint protection circuit is not used, insert a resistor in
parallel with this capacitor.
CLD
27
Sets the phase locked signal mask time. Insert a capacitor between this pin and ground. Leave this pin open if there is no
need to mask.
FGS
28
FG Schmitt output. This is an open-collector output.
LD
29
Phase locked state detection output. This output goes to the on state when the PLL phase is locked. This is an open-
collector output.
S/S
32
Start/stop control input. Low: start, High or open: stop.
CLK
33
Clock input. The maximum input frequency is 10 kHz.
BRSEL
34
Deceleration control switching input. Low: Reverse torque control, High or open: free running.
An external Schottky barrier diode is required on the output low side if reverse torque control is used.
PH
35
Smoothes the RF waveform. Insert a capacitor between this pin and ground.
VREG
36
5 V regulator output (control circuit power supply). Insert a capacitor between this pin and ground for power supply
stabilization.
VM1
37
Output block power supply. Short this pin to VM2.
VM2
38
Output current detection. Insert a resistor between this pin and V
CC
1.
The maximum output current IOUT is set to be IOUT = 0.5/Rf.
V
CC
2
39
Upper diode cathode connection. Short this pin to V
CC
1.
V
CC
1
40
Power supply. Insert a capacitor between this pin and ground to assure that noise does not enter the IC.
GND3
44
Output circuit block ground.
FRAME
Connect this pin to ground. The FRAME pin is connected internally to the metal surface on the back of the package. To
improve thermal dissipation, solder this metal surface to the PCB.
NC
2, 4, 5, 7
18, 20, 30
31, 41, 42
43, 45, 47
48
Since these pins are not connected to the IC internally, they can be used for wiring connections.
