About IMON pin of LT3086


Let me ask about LT3086.

I want to use LT3086EDHD without IMON & CDC function. Then I confirmed that CDC pin can float.

Also if I don't use ILIM function that ILIM pin can connect GND that. Then I think IMON can connect to GND in case of IMON&ILIM is same pin. But LT3086EDHD is separated that these pin.

Is it ok that IMON of LT3086EDHD to connect to GND.

Best regards

Based on the datasheet, only if the IMON reads 0.8V then it would limit the output current. So grounding this pin should be fine so it always read 0V essentially disabling the pin's function.
