When excessive current flows owing to output shortcircuit or so, ringing occurs by inductance of power source line to IC, and
may cause bad influences upon IC operations. In order to avoid this case, connect a bypass capacitor by VDD pin and GND
pin of IC. 1uF or higher is recommended.
Pull up flag output by resistance 10kΩ ~ 100kΩ.
Set up value which satisfies the application as C
This system connection diagram doesn’t guarantee operating as the application.
The external circuit constant and so on is changed and it uses, in which there are adequate margins by taking into account
external parts or dispersion of IC including not only static characteristics but also transient characteristics.
In BD6512F/BD6513F, there are cases where over current detection error flag is output to inrush current at switch on or at
insertion of active line of peripheral devices. In the case of erroneous detection inBD6512F/BD6513F, use RC filter shown in
Fig. 90 for FLAG output.
