HI All,
We have several problems trying to activate AICO service. As we understand the datasheet it seems that if AICO_EN register is “1”. When Vin(5V normally) is under Vin_min (configured to 4.4V) an interrupt is raised (INT pin) and Iin_dpm dynamically is decreasing until Vin is stable, then Ilim = Iin_dpm. Is that correct? It seems that the AICO service is not working.
The below image shows how voltage decreases under 4.4V and the interrupt is raised, but Iin_dpm doesn’t change. Any idea about what is wrong??
Thanks
