Terminal Designation

Note: 1. The RST terminal is connected to an internal 100 k

Ω pull-up resistor. When this terminal is not used, connect a 0.1 μF capacitor between

the terminal and ground to prevent misoperation at power-on.

2. Connect the CAP terminal to a capacitor for smoothing power supply. Connect a 0.1

μF capacitor between the terminal and GND.

3. The VZ1 and VZ2 terminals are for driving output protection. Connect them to the power source of a driving system. When several driving system

power supplies are used, connect the terminals to the highest potential among them. When these terminals are not used, leave them open.

4. Always leave the TST1 and TST2 terminals open.

5. Leave unused output terminals open.
