Hi everyone :)

I´d like to build a linear battery charger using a uC to act like MAX712...
https://www.maxim-ic.com/quick_view2.cfm/qv_pk/1666/ln/en

I need some suggestion how to implement the "Current and Voltage Regulator" block while supplying a load or not ...

Timer, Delta V and Temp comparators blocks will be done with the uC.


Thanks in advance
Rafael

There are several app notes and ref designs at the microchip site. Most use their battery charger chips but this doc may help you:
