6 FAQs about [MCU charges lithium battery]

Can a lithium-ion battery charger charge a 5V battery?

How to charge a lithium ion battery?

The fast charge (constant current) and constant voltage charging are the most important stages during a recharge process. Most Li-ion batteries have a fully charged voltage of 4.1 V or 4.2 V. The battery is first charged with a constant current of 1C until the battery voltage reaches 4.1 V or 4.2 V.

Can a mcp73831 charge a Li-ion battery at the same time?

The problem with charging and using a Li-ion battery at the same time is that end of charge is not properly detected. The MCP73831 uses the current level at the end of the constant voltage stage for charge termination. Aha that makes sense, thanks for clearing that out. I think i will leave the schematic as it is and not remove the switch.

What is a battery charger with load sharing?

This article goes through creating a battery charger with load sharing (also known as power-path) that can properly charge the battery and have the main circuit run normally.

What are the advantages of MCU-controlled charging method?

Advantages of the MCU-controlled charging method include safe charging, time efficiency, and low cost. Battery capacity (C), expressed in milliamp-hours (mAh), is a measure of battery life between charges. Battery current has the units of C-rate.

Are MSP430 microcontrollers good for a Li-ion battery charger?

All trademarks are the property of their respective owners. NOTE: Page numbers for previous revisions may differ from page numbers in the current version. The MSP430 microcontrollers are a good fit for a Li-ion battery charger solution, because of integrated peripherals like the high-resolution ADC and watchdog timer.
