Hello, and thank you for your time. We have designed an NPM1100 into a product, and are unclear on if the behaviour of the charge pin is correct (nor indeed what exactly is the expected behaviour).
Our expectation is the following: when charging is actively occurring, thats to say current is flowing into the battery, the charge pin should be active (low). In all other cases, the charge pin should be inactive (high).
We have noticed the charge pin low when there is no Vusb and our device is operating off the battery. Is this correct, that the charge pin is active when charging could potentially occur (battery voltage within the charge range) even if it is not actually occurring?
Thank you!
