... The LED on the EV kit is driven by the CHG pin. Depending on the Li+ cell’s charging status, the pin is low or high impedance, thus turning the LED ON or OFF. If the Li+ cell cannot be charged to 2.5V in less than 1/4 of the total programmed charge time, the charger will go into fault mode. During t ...

Electrical ballast



An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
