Here is a tried and tested sample circuit of a Li-Ion battery charger that can be used to charge any 3.7V Li-Ion battery using a 5VDC (USB, Solar Panel…) power supply. At the heart of the circuit is ...

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 ...

Recharging is a necessity for all portable wireless devices. When such devices are recharging, however, they have a tendency to overheat. Linear Technology Corp. wants to address this problem with the ...

Dealing with inrush currents in industrial systems? PTC thermistors can handle higher energy, reduce component count & ...

Electronic systems are often subject to the power limitations imposed by their power supplies and batteries, and the maximum power available from those Jeffrey S. Mueller, Ph.D., Maxim Integrated ...

Fast charging has become a must-have feature in today’s phones. It keeps our batteries topped up throughout a busy day and has us back in action in mere minutes. However, there are a variety of ...

The simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens.

The current flowing in a parallel circuit can be investigated by connecting the circuit below. Once more, put one ammeter in position A 1 and record the reading in a suitable table. The current in a ...

If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...
