Rectifier Switch

R5590x Typical Application: The R5590x allows batteries to be placed in any direction without regard to positive or negative polarity.

Protection against reverse insertion of a dry cell, generally, mechanically or using diode method is common. These method limits operation if reverse insertion happens. Ricoh offers direction free insertion of a dry cell with the R5590. The R5590 reduces the energy loss of Vf by a diode and rectifies and realizes dry cell direction free insertion.
