Over the last couple of decades the use of rechargeable batteries has grown enormously, and for most common applications there are ASICs[1] which control battery management with very little additional ...

I will be talking about single-series (1sXp) cell configurations, for a simple reason – multiple-series configurations are not something I consider myself as having worked extensively with. The single ...

The Design Idea in Figure 1 indicates a low-battery condition in an audio test instrument that is powered by four AA cells. As the instrument was otherwise an all-discrete design, this same approach ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently in practical circuits. A Joule Thief circuit is a small, energy-efficient ...

A new type of battery combines negative capacitance and negative resistance within the same cell, allowing the cell to self-charge without losing energy, which has important implications for long-term ...

Fig 1. The ripple-eater design, essentially a filter with a follower, rejects as much as 40 dB in ripple and continues operating even as the supply voltage drops to low levels. Fig 2. With the ...

The following circuit uses a low-power CMOS comparator and an LED to indicate low-battery voltage without causing excessive current drain. To view the application note, click on the URL below. Circuit ...
