Hello,

Is there a way to read the output current value?

Thanks,

Hi Michael,

You're wanting to be able to read the output current from the output pins? We can't do that from the device but you could read the output voltage with an oscilloscope and calculate the current draw from the device based on the voltage and the load's impedance. If you have a special current probe for the oscilloscope you can use that alternatively.

Regards,

Hi Robert,

Thanks for the response. I think the customer's intent is to read the output current into their micro. I don't think it is possible with this device, but just thought I'd check.

Thanks,

Michael

Hi Michael,

No problem. You are correct. Current sense isn't integrated into this device. They would have to use external circuitry.

Best Regards,
