6 FAQs about [Lithium battery and power supply share circuit]

What is a lithium battery charger circuit?

In this tutorial, we are going to make a “Li-Ion Battery Charger Circuit”. Lithium-based batteries are a flexible method for storing a high amount of energy. They have one of the most elevated energy densities and specific energy (360 – 900 kJ/kg), as compared to other rechargeable batteries.

What is load sharing power path control?

The load sharing power path control (Q2, D1, R6) interrupts the connection between the battery and the load when an external power supply is connected. In this case, the load is powered by the external power supply while the battery is being charged. This protects the battery and increases its lifespan.

What is a lithium polymer battery?

Lithium Polymer batteries, or LiPo batteries, are a newer, more advanced version of lithium-ion batteries. Like their predecessors, they have specific charging and discharging parameters that must be followed. However, LiPo batteries are more lenient than lead-acid batteries when it comes to charging rates.

Can lithium polymer batteries be charged?

Lithium polymer batteries are the preferred choice of power source for electronic devices due to their lightweight, high energy density, and longer lifespan. However, charging them can be tricky, as they have strict charging and discharging parameters. But worry not, as we have a solution for you.

How does a power path IC work?

This means that when charging, the IC will supply power to the system load from the wall supply, just like in my example 2. If the system load then draws more than the wall supply can source, it switches to allow the battery pack to make up the difference. Thus, a power path IC can supply the same power whether charging or not.

What is a Li-ion battery charger circuit?

Target Li-Ion battery connected between Pin3 and ground. The main application of this circuit is used to charge the Li-ion batteries. In this tutorial, we are going to make a "Li-Ion Battery Charger Circuit". Lithium-based batteries are a flexible method for storing a high
