But i have a question turns out to be rather a silly one. The tp4056 chip is a lithium ion battery charger for a single cell battery protecting the cell from over and under charging. Battery charger ics products utilize our battery charger parametric search tools to quickly find the best charger to fit your design specifications. The lipo battery i have has a separate charging pins.

I went through lithium polymer battery charger circuit as i request few days back. It tolerates an input voltage up to 28 v which eliminates the input over voltage protection circuit required in handheld devices. It has two status outputs indicating charging in progress and charging complete. 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 also has a programmable charge current of up to 1a. These battery charger ics are offered in linear or switching topologies and are completely autonomous in operation. Analog devices offers a broad portfolio of high performance battery charger ic devices for any rechargeable battery chemistry including li ion lifepo4 lead acid and nickel based for both wired and wireless applications. It has 4 pins in total.
