Abstract
Various systems, methods and apparatuses are provided herein for limiting power dissipation in a switch. As one example, a method for limiting power dissipation is disclosed. The method includes monitoring current through the switch, and based at least in part on detecting that the current is at least as great as a predetermined current limit, regulating the current to the predetermined current limit. The method also includes measuring an amount of power dissipated in the switch while the current is being regulated, and opening the switch when the amount of power has reached a predetermined power limit.
