Chargers

Cordless power tool battery chargers require efficient rectifiers and reliable overcurrent and overvoltage protection devices. A block diagram shows which MOSFET ac–dc converters, TVS diode arrays, metal oxide varistors, Schottky diodes, and miniature fuses made by Littelfuse that battery charger designers can use.
