Hi

g.prabhu

,

Controlling OUT11 is not different that controlling other HS output like OUT7 to OUT

Please double check your SPI register configuration.

Best Regards.

Hello Prabhu,

once you have turned on OUT11, could you please read all register contents and provide it here?

Thank you.

Regards.

I'm sorry Prabu,I don't understand really the problem.

Is OUT11 working properly or not?

Hi Ignazio,

OUT11 Pin is working and it is always High. I'm not able to make it Low. 

I need one more support regarding the varying the voltage levels 12V, 9V and 6V on the OUT Pins. Kindly help us how to do this. And is there any sample code or development platform available for this IC l9950 ?

Regards

Prabhu.

Hi Prabhu,

Is OUT11 always high even if loaded with some resistor value?

If is always ON and able to supply some loads, the IC could be damaged.

What do you mean by varying the output voltage of the OUT Pins?

Those outputs are High Side Drivers means that they bring out the Battery Level when active.

If the Battery level is 12V they will give you 12V ou output.

If you supply with 9V they will give you 9V and so on.
