When charging the battery, switch off the load, and when loading the battery, switch off the charger. Alternatively use a PMOSFET, a resistor and a Schottky diode (See page 2 on how to do this). Lithium batteries can not absorb overcharge - the current must be cut off after charging. If not there could be thermal runaway.
Li-ion battery charging ICs play a vital role in managing the charging process, ensuring safe and efficient power delivery to the battery. Here are some essential considerations when evaluating these ICs: Maximum charge current: The Maximum charge current determines how quickly the battery can be charged without damaging it.
An easy way to charge a lithium battery is to use Microchip’s MCP73827 lithium charger IC. The MCP73827 biases an external p-channel MOSFET to provide power to the lithium cell. The MCP73827 senses voltage across a low-ohm sense resistor sensed to regulate the charge current for constant current charging and charge termination.
Even though most common Li-ion or Li-po batteries have a typical full charge voltage of 4.2V, it may not be the case for all the batteries in the market. So, for this reason, there are multiple variants of the charging ICs available with different full charge termination voltages.
The TP5000 is another popular Li-ion battery charger IC is known for its high efficiency and reliability. It supports single-cell lithium-ion or lithium polymer batteries with 3.6 or 4.2V termination voltages. It also offers adjustable charging parameters to accommodate various battery sizes and chemistries.
For a 2500 mAh cell, the standard charge current would be 1250 mA. The battery cell will have most of its charge when the battery voltage reaches 4.1 V or 4.2 V. At this point, the current going into the battery gradually decreases. When the current drops below a datasheet value, charging should be terminated.
