Abstract
An input power circuit for a battery-powered device, such as a toy or consumer electronic device, includes a polarity correction circuit portion. The device includes a first input terminal and a second input terminal, a first output terminal and a second output terminal, and a diode with a forward voltage drop of about 0.5 volts or less. In embodiments, the polarity correction circuit portion is configured to provide a positive voltage polarity at the first output terminal and a negative voltage polarity at the second output terminal for any polarity of power at the first input terminal and the second input terminal. The polarity correction circuit portion can include a diode bridge, and the diode may include a Schottky diode or a germanium diode.
