Page 4 MD123 Application Notes In multiple power supply application, to get suitable input voltage range from external controller, it is suggested to connecting VDD pin to the same power source with external controller and the voltage of VDD, VS1 and VS2 pins can be expressed by V(VDD) ≥ V(VS), where V(VDD) is the voltage of VDD and V(VS) is the voltage of VS1 and VS2 pins. To increase system stability, it is suggestion to connect a resistor RVDD about 100Ω between battery power and driver's VDD pin as shown on application circuit. The VR pin is a voltage reference output in DIP14 package, let VR pin in floating state in the application. The power dissipated by the IC varies widely with the supply voltage, the output current, and loading. It is important to ensure the application does not exceed the allowable power dissipation of the IC package.
