Connects to a PNP-type voltage parator. Overcurrent detection current setup pin. When this pin is grounded, the ISD value is increased by 1A (typically) . 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. Grounded 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. 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. Power supply pin for the output section Power supply pin for the control section. This pin is pletely separated from the VCC pin. When this pin is opened or grounded, the output turns off to reduce the current consumption below 100µA. If standby mode is not needed, the pin connected to VCC. Not connected. (Electrically, this pin is pletely open.) TRUTH TABLE DI1 H L H L H/L Input DI2 H H L L H/L Output M (+) M (- ) Output...
