Abstract

A battery charger contact protection circuit (10) including a metal oxide field effect transistor (16) is provided. The battery charger contact protection circuit (10) adds the advantages of reducing heat, reducing cost, and providing flexibility in the charging of various types of battery chemistries. Excess heat is eliminated by reducing the amount of charge dissipated by the contact protection circuit.
