Abstract
A smart switch system comprising one or more switching devices. Each one of the switching devices include a first pin, a second pin, a current indication pin, a system current limit pin and a power switch for electrically coupling the first pin to the second pin when the power switch is turned on. Each switching device may adaptively adjust an operation current limit value of the switching device based on a system total current limit value received or set at the system current limit pin and a system current indication signal received at the current indication pin.
Claims19
A smart switch system, comprising:
- a plurality of switching devices, wherein
- each one switching device of the plurality of switching devices comprises a first pin, a second pin, a current indication pin, a system current limit pin and a power switch coupled between the first pin and the second pin, and wherein the current indication pin is configured to receive a system current indication signal indicative of a real-time total output current of the smart switch system, and wherein the system current limit pin is configured to receive or set a system total current limit value ISYSLIM of the smart switch system, and wherein
- each one switching device of the plurality of switching devices has an operation current limit value ICC and is further configured to adaptively adjust its operation current limit value ICC to change in a same direction as the system total current limit value ISYSLIM, and is further configured to adaptively adjust its operation current limit value ICC to change in an opposite direction to the system current indication signal.
