Application Information

When excessive current flows owing to output short-circuit or so, ringing occurs by inductance of power source line to IC,

and may cause bad influences upon IC actions. In order to avoid this case, connect a bypath capacitor CIN by VIN terminal

and GND terminal of IC. 1μF or higher is recommended. In order to decrease voltage fluctuations of power source line to IC,

connect a low ESR capacitor in parallel with CIN. 10μF ~ 100μF or higher is effective.

Pull up /OC output by resistance 10kΩ ~ 100kΩ.

Set up value which satisfies the application as CL and Ferrite Beads.

This system connection diagram doesn’t guarantee operating as the application.

When using the circuit with changes to the external circuit constants, make sure to leave an adequate margin for external

components including static and transitional characteristics as well as dispersion of the IC.
