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 ...

When three resistors are connected in series to a battery, they form a simple yet fundamental circuit that demonstrates key ...

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 ...

A high voltage controller and power manager IC combines with virtually any externally compensated DC/DC power supply IC to create a full-featured battery charger. The LTC4000 only requires an external ...
