The circuit was designed to create a spare and reserve power source with the use of batteries during the absence of power from the mains. BD139 – NPN power transistor used for driver stages in hi-fi ...

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 ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...

When the battery voltage falls below the lockout threshold, the circuit monitors the voltage of a Li-Ion battery and disconnects the load to prevent deep discharge. A vehicle that runs on batteries ...

Because stationary batteries and 48VDC power systems serve as lifelines for telecommunication networks, the reliability of these systems is of the utmost importance. Many system designers rely on ...

As we shift away from gas- and diesel-powered engines and toward electrification, a recurring problem comes up: Batteries are heavy, and heavy is the enemy of efficiency. The quest for cheaper, ...

To make something work using electricity there needs to be an electrical circuit; a circuit is a complete loop that electricity can move around. Electricity moves from the power source (the battery or ...

A circuit is a closed loop containing various components. Electrical current flows around the circuit. Scientists use symbols to represent the different components in a circuit. Symbols are simplified ...
