Symbol
Description
1
3
VCC
Power supply pin. This pin has a function to turn off the output when the applied voltage exceeds
27.5 V, thus protecting the IC and the load.
FIN
GND
Grounded
8
9
DI1
DI2
Output status control pin.
Connects to a PNP-type voltage comparator.
15
M (
+)
Connects to the DC motor. Both the sink and the source have a current capacity of 1.5 A.
Diodes for absorbing counter electromotive force are contained on the VCC and GND sides.
16
M (
)
Connects to the DC motor together with pin 15 and has the same function as pin 3. This pin is
controlled by the inputs from pins 8 and 9.
2, 4~7
10~14
17~20
NC
Not connected. (Electrically, this pin is completely open.)

Note 1: Brake mode comes into effect when both M (
+) and M () go low.
Note 2: Stop mode comes into effect when both M (
+) and M () turn OFF.
