Hello
A charge current of 10mA with 1mA termination is very low. What are the customer's requirements?

Hi Johns,

Thanks for reply. their power supply side is something like solar energy, so can only provide a about 2mA current. their charging target is a Li-battery.

Hello
This is a very low value, do not have anything off the shelf that can do this.

Very low currents like this will also have problems with when and how to terminate charge.
