Pin Function
Pin No.
Pin name
Function
Equivalent circuit
1
FG
FG pulse output. This pin outputs a Hall
sensor system equivalent pulse signal.
2
RD
Motor lockup detection output.
Output is fixed high when motor is locked up.
1
2
3
CT
Motor lockup detection time setting.
When the motor lockup condition is detected,
the protection time period before the
protection circuit is activated is set by
connecting a cacacitor between this pin and
ground.
VREG
3
4
OSC
Motor startup frequency setting. A capacitor
must be connected between this pin and
ground. The startup frequency is adjusted by
controlling the charge/discharge current and
capacitance of the capacitor.
VREG
4
5
GND
GND pin
6
VG
Charge pump step-up voltage output.
A capacitor must be connected between this
pin and the VCC pin or ground.
7
CP
Charge pump step-up pulse output pin.
A capacitor must be connected between this
pin and the CPC pin (pin 8).
8
CPC
Charge pump step-up pin.
A capacitor must be connected between this
pin and the CP pin (pin 7).
VREG
VCC
7
8
6
13
VCC
Power supply for the IC and motor.
Capacitors must be connected between
these pins and ground.

10
UO
VO
WO
Output pins. Connect these pins to the U, V,
and W of the motor coil.
9
RF
Output current detection pins. The drive
current is detected by connecting a resistor
between these pins and ground.
