Pin Description
Equivalent Circuit
25
PWM
PWM oscillator frequency setting.
Connect a capacitor between this pin and ground.
A frequency of about 21kHz can be set by using
a 2200pF capacitor.
26
GND1
Ground
(For circuits other than the motor drive output system)

IN1+
IN1-
IN2+
IN2-
IN3+
IN3-
Hall effect sensor inputs
High when IN+ > IN-, low for the reverse state.
Signal inputs with an amplitude (differential) of at least
100mVp-p are desirable for the Hall inputs.
If noise is a problem, connect capacitors between
the IN+ and IN- inputs.
33
F/R
Forward/reverse control
Low: forward, high or open: reverse.

24,35
NC
No connection.
The NC pins may be used for wiring connections.
FRAME
Frame connection
The FRAME pin is connected internally to the IC surface
metal parts. Both must be used in the electrically open
state.
