Using an MIC79050 after this type of charger is ideal for lithium-ion battery charging. The only obstacle is end of charger termination. Using a simple differential amplifier and a similar comparator and reference circuit, similar to Figure 5-1, completes a single cell lithium-ion battery charger solution.
The battery charger for the 2-cell lithium-polymer battery is an MCP73844 dual cell Lithium Polymer charge management controller. It uses an external pass transistor (NDA8434 P-channel enhancement MOSFET) to provide up to 6A of charging current, but the 100m Ω sense resistor R6 limits the charging current to 1.1A.
