... In that example, a Single-ended Primary Inductive Converter (SEPIC) is used to provide a con- stant charge current to the series-connected batteries. The MCP1630 is used to regulate the charge current by monitoring the current through the battery sense resistor and providing the proper pulse width. The PIC16F818 monitors the battery voltage to provide a termination to the charge current ...
