Lithium Polymer Battery Charger Ic

I went through lithium polymer battery charger circuit as i request few days back.

Lithium polymer battery charger ic.

The mc34673 is a cost effective fully integrated battery charger for li ion or li polymer batteries. The board design provides constant current charging followed by constant voltage charging with automatic charge termination. It has 4 pins in total. A charge cycle includes trickle constant current cc and constant voltage cv charge modes.

It also has a programmable charge current of up to 1a. Our broad portfolio of battery charger ics provide safe charging for 1 to 3 cell li ion li li polymer nimh nicd lead acid and rechargeable batteries of other chemistries in various sizes. It tolerates an input voltage up to 28 v which eliminates the input over voltage protection circuit required in handheld devices. High efficiency switching battery chargers provide low heat and fast charging solutions up to 9a for high capacity batteries.

These battery charger ics are offered in linear or switching topologies and are completely autonomous in operation. The mcp73855 battery charger evaluation board is set up to evaluate simple stand alone linear charging of single cell li ion li polymer battery packs the battery packs are not included. It has two status outputs indicating charging in progress and charging complete. What are the modifications required for that particular battery.
