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.
