Application Notes
In multiple power supply application, to get suitable input voltage range from external
controller, it is suggestion connecting VDD pin to the same power source with external
controller.
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.
