Functions
FR
6
Forward/reverse select pin.
This pin voltage determines forward/reverse. (Vth = 1.25V TYP at VCC = 5V)
GND for others than the output transistor.
Minimum potential of output transistor is at Rf pin.
GND
7
FGIN (-)
8
Input pin for the FG amplifier to be used with inverted input.
A feedback resistor is connected between this pin and FG OUT.
FGIN (+)
9
Non-inverted input pin for the FG amplifier to be used as differential input.
No bias is applied internally.
FG-OUT
10
FG amplifier output pin.
Resistive load provided internally.
CTL
12
Speed control pin. Control is performed by means of constant current drive which is applied by current feedback from Rf.
Gm = 1.06A/VTYP at Rf = 0.5
LIM
13
Current limiter function control pin.
This pin voltage is capable of varying the output current linearly.
Slope = 0.71A/VTYP at Rf = 0.5
FC
14
Speed control loop’s frequency characteristics correction pin.

VCC
21
Power supply pin for supplying power to all circuits expect output section in IC; this voltage must be stabilized so as to
eliminate ripple and noise.
VS
22
Power supply pin for supplying power to output section in IC.
ADJ
23
Pin to be used to adjust the torque ripple correction factor externally.
When adjusting the correction factor, apply voltage externally to the ADJ pin through a low impedance.
Increasing the applied voltage decreases the correction factor; lowering the applied voltage increases the correction
factor.
The rate of change, when left open, ranges approximately from 0 to 2 times.
(Approximately VCC/2 is set internally and the input impedance is approximately 5k
.)
Output current detection pins. Current feedback is provided to the control blocks by connecting Rf between the pins and
GND. The operation of the lower over-saturation prevention circuit and torque ripple correction circuit depends on the pin
voltage. In particular, since the oversaturation prevention level is set by the pin voltage, decreasing the Rf value
extermely may cause the lower over-saturation prevention to work less efficiently in the large current region. The PWR
pin and SENSE pin must be connected.

1
U-phase output pin.
V-phase output pin. (Built-in spark killer diode)
W-phase output pin.
GSENSE
5
GND sensing pin.
By connecting this pin to GND in the vicinity of the Rf resistor side of the Rf included motor GND wiring, the influence
that the GND common impedance exerts on Rf can be excluded. (Must not be left open.)
