BQ24295 Smart Battery Charger IC with Boost + OTG
This BQ24295 IC is like a super smart charger chip. This one is not just for charging battery, but also doing many other jobs like boost converter, USB detection, power path control, and even OTG (host power supply). So we can say that this is a full battery charging and power management IC. Let us […]
12V Battery Charger Circuits [using LM317, LM338, L200, Transistors]
In this article I will be discussing a list of simple 12V battery charger circuits which are very easy and cheap by its design yet extremely accurate with its output voltage and current specs. All the designs presented here are current controlled meaning their outputs will never go beyond a predetermined fixed current level. UPDATE: […]
NiMH Battery Charger Circuit
A single state-of-the-art chip, a transistor and a few other inexpensive passive components are the only materials required for making this outstanding, self regulating, over charge controlled, automatic NiMH battery charger circuit. Let’s study the whole operation explained in the article. Main Features: How the Charger Circuit Works Referring to the diagram we see a […]
One Transistor Automatic Battery Charger Circuit
This one transistor cheap battery charger circuit is designed to automatically switch OFF the supply to the battery as soon as the battery has reached its full charge level. A very simple single transistor automatic battery charger circuit is I have I have explained in this article, which uses just a single transistor for the […]
Self Regulating Battery Charger Circuit
In this post I have explained how a neat little self regulating automatic battery charger circuit can be made using just two inexpensive transistors. This circuit will automatically regulate the charging supply to the battery depending on its charge level, by switching the input supply ON and OFF periodically. How it Works As can be […]
