Texas Instruments bq25171-Q1 Linear Battery Charger is an automotive rated 800mA linear charger for 1-cell and 2-cell Li-Ion, Li-Polymer, and LiFePO4, in addition to 1-cell up to 6-cell NiMH battery applications. The device has a single power output that charges the battery. The system load can be placed in parallel with the battery as long as the average […]
The LIR1220 is a 12.5 mm. lithium-ion rechargeable coin cell. It is a relatively new technology. Traditionally, li-ion coin cells are non-rechargeable but for some situations, rechargeable compact cells are desired. Coin cells like CR2032 are ultra-compact and are used in a variety of compact systems like wearables and if something with this form factor

This cheap and easy to build NiCd/NiMH Battery Charger is suitable for automatically charging a wide range of batteries for many applications. Proper chargers are usually expensive and cheap chargers supplied with the original equipment often incorrectly charge the cells and dramatically shorten their life. This ‘intelligent’ charger was designed for high current and rapid

You get a really good feeling when you plug in some lights and appliances and power them with your own electricity from the sun or wind. You get a really bad feeling when you run those items and the clouds come for days or weeks or months on end. The batteries get lower and lower.
Grid Powered Battery Charger – The Plans using PIC16F676 Read More »
The first step to designing a battery charger is choosing a battery charger IC from the vast field of available solutions. To make an informed decision, a design team must first clearly define the battery parameters (chemistry, cell count, etc.) and the input parameters (solar, USB, etc.). The team must then search for chargers that
