Abstract
A battery protection structure is described. The structure provides battery overcharging protection while allowing for minimal battery voltage drop during normal battery operation. One resistance element sets voltage drop during normal operation, and the sum of two resistance elements sets the maximum battery charging current which will be allowed. The structure provides protection against single component failures.
