Parallelling multiple power switches

A system, comprising:

• a first temperature sensing element thermally coupled to a first power switch and arranged to generate a temperature indication of the first power switch;
• a second temperature sensing element thermally coupled to a second power switch and arranged to generate a temperature indication of the second power switch;
• a first power switching circuit coupled to receive a power switching control signal and arranged to control the first power switch in response to the power switching signal;
• and
• a second power switching circuit coupled to receive the power switching control signal, coupled to receive the temperature indication of the second power switch, and arranged to generate a first power switching delay in response to the temperature indications of the first and second power switches, wherein the second power switch is activated in response to the first power switching delay, and wherein drains of the first and second power switches are coupled to a common switched node.

A method, comprising:

• generating a first temperature indication in response to a temperature of a first power switch;
• generating a second temperature indication in response to a temperature of a second power switch;
• receiving a power switching control signal for activating the first and second power switches;
• delaying the received power switching control signal in response to the temperature indications of the first and second power switches;
• and
• activating the second power switch in response to the delayed power switching control signal.
