Hi,

we want to use the Murata UMAC Lithium ion battery as the primary power source. It has a charge voltage of 2.7V with a capacity of 3mAh, more than enough for our case.

According to the data sheet of DA1468x, unfortunately the charge voltage of the built-in Constant Current/Constant Voltage charger can only be set down to a minimum of 3V.
Is there any other option to charge this battery type with the built-in charger? Maybe with a few additional components (not talking about a seperate charger IC)?

Thank you for any hint
