The algorithm for this circuit is that the blocking MOSFET must be disabled if the battery voltage exceeds the battery charger output voltage. In this circuit MN1 is connected in the low side of the ...

Improved smaller-dimension circuit-protection devices have been introduced by STMicroelectronics to enable safer use of universal chargers with the aim of reducing the number of battery chargers ...

As the number of portable devices powered by a single Li-ion or Li-polymer cell continues to grow, semiconductor vendors maintain their quest to develop ever-more compact and robust battery-charger ...

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 ...

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 ...
