Lithium Polymer Battery Charger Ic

The board design provides constant current charging followed by constant voltage charging with automatic charge termination.

Lithium polymer battery charger ic.

The lipo battery i have has a separate charging pins. The mc34673 is a cost effective fully integrated battery charger for li ion or li polymer batteries. The tp4056 chip is a lithium ion battery charger for a single cell battery protecting the cell from over and under charging. I went through lithium polymer battery charger circuit as i request few days back.

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. But i have a question turns out to be rather a silly one. What are the modifications required for that particular battery. A charge cycle includes trickle constant current cc and constant voltage cv charge modes.

These battery charger ics are offered in linear or switching topologies and are completely autonomous in operation. High efficiency switching battery chargers provide low heat and fast charging solutions up to 9a for high capacity batteries. It has 4 pins in total. Battery charger ics products utilize our battery charger parametric search tools to quickly find the best charger to fit your design specifications.

It has two status outputs indicating charging in progress and charging complete. It tolerates an input voltage up to 28 v which eliminates the input over voltage protection circuit required in handheld devices. 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. Whether you need a single cell linear charger for space constrained applications or a single to multi cell switching charger with high charging current for fast and cool charging our quick.
