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