Abstract
In one example, a method includes determining, by a temperature sensor, a temperature of a device that controls an amount of current flowing to a load, and determining, based on the temperature of the device, a threshold current. The method also includes, in response to determining that the amount of current flowing to the load is greater than the threshold current, adjusting the amount of current flowing to the load.
Claims15
A method comprising:
- providing, by a device, an amount of current to a load;
- measuring, by a temperature sensor, a temperature of the device;
- adjusting, based on the temperature of the device, a current trip threshold that is greater than zero such that the current trip threshold decreases as the temperature of the device increases;
- and
- in response to determining that the amount of current flowing to the load is greater than the current trip threshold, deactivating the load.

A system comprising:
- a device configured to provide an amount of current to a load;
- a temperature module configured to determine a temperature of the device;
- a current threshold module configured to determine, based on the temperature of the device, a current trip threshold that is greater than zero, wherein the current trip threshold decreases as the temperature of the device increases;
- and
- a current control module configured to, responsive to determining that the amount of current flowing to the load is greater than the current trip threshold deactivate the load.
