It is available in a tiny package, hence most suitable for compact handheld and portable applications.
Need help with my liion charger circuit (bq24618) with 5V output. Power management forum
During discharge of a Li-ion battery, ions move from the negative electrode through an electrolyte to the positive electrode, causing electrons to move in the opposite direction around the circuit to power the load. Once the ions in the negative electrode are used up, current stops flowing.
LiIon Battery Charger Using IC 555 Homemade Circuit Projects
Li-ion batteries are often charged to 4.2 V/cell at 0.5C or less to near 1C capacity, sometimes followed by a slower charging rate. The challenge is to keep the temperature rise to under 5ยฐC. A higher temperature during charging could lead to a catastrophic event such as fire.
Battery Charger Circuit Schematic
This lithium ion battery charger circuit is very similar to the previous, with two differences. First, instead of just using the MOSFET, you also pass the input supply to the load through a diode. By connecting the FET gate to the input power supply and a diode (normally a Schottky) in series, the system load takes power from the input supply.
