DESCRIPTION
1

DI1
DI2
Output status control pin.
Connects to a PNP-type voltage comparator.
3
Adj
Overcurrent detection current setup pin. When this pin is grounded, the ISD value is increased
by 1A (typically) .
4
M (+)
Connects to the DC motor. Both the sink and the source have a current capacity of 3A. Diodes
for absorbing counter electromotive force are contained on the VCC and GND sides.
6
GND
Grounded
8
M ()
Connects to the DC motor together with pin 4 and has the same function as pin 4. This pin is
controlled by the inputs from pins 1 and 2.
9
VSD
Overvoltage detection pin. When a voltage higher than 27.5V (typically) is applied to this pin, the
output turns off (enters stop mode) .
Generally, the pin is directly connected to the VCC pin (pin 10) . If overvoltage protection is not
needed, the pin is opened or grounded.
10
VCC
Power supply pin for the output section
11
VS
Power supply pin for the control section. This pin is completely separated from the VCC pin.
12
ST
When this pin is opened or grounded, the output turns off to reduce the current consumption
below 100A.
If standby mode is not needed, the pin connected to VCC.
5, 7
NC
Not connected. (Electrically, this pin is completely open.)
