QI have the ADP5585's interrupts enabled in register 0x3C and according to
register 0x01, both the OVERFLOW and EVENT interrupts have occurred (refer to
But the problem is, that the EVENT_INT line (pin 16) from the ADP5585 does not
assert. It is constantly low, even when I test the pin on the chip by itself.
Are there any hardware requirements on the EVENT_INT line?
AThe EVENT interrupt is enabled and the /INT pin should assert.
There are two things to check here.
(i) Can you ensure that the /INT pin has a pull-up resistor, as it is
open-drain. A 1Kohm pull-up resistor is a good choice.
(ii) If you already have the pull-up resistor in place and it still doesn't
work correctly, can you try the sequence attached, based on your register
settings (including suggested register changes to be made).
