current sourcen SLG46620V

Dear

 

I would like to know if it is possible to generate current source from greenpack in this device. Thanks

Regards

danmalper1, 

Thanks for you question, 

SLG46620 has built-in 100uA constant current source. In order to activate it you may take ACMP and enable the setting "Input 100uA current source"(see the attachement). In this case PIN6 will be constant current source and you can use it for external circuits or supply some sensors. Let me know if you have some questions

Best regards,

Dear Olehs, 

Dear Olehs, 

Thank you for reply, It is ok, but I am not sure if I understand, is it possible that inut to Pin6 were a voltage source and use that output from ACMP as current source? In this case, that current would be maximum to 100uA?

Thank you again

regards

Thanks for your question, 

ACMP in GPAK is not as usual OpAmp, it doesn't have the analog output. So, unfortunately, you can't create the current source using this approach.   

If it will be helpful, you can use the approach how we create the constant current LED Driver using GPAK. See the link below:
