Abstract: An apparatus comprises an input node, a power rail to power a circuit load, and multiple current paths coupled in parallel with each other between the input node and the power rail. Each current path respectively provides a sense output to indicate current in the path and a current switch having a control input to control the current in the path. A control circuit, coupled to each control input individually and to each sense output individually, controls the current in each path individually based on the indicated current therein after a non-zero input voltage is initially applied to the input node, such that all of the paths concurrently conduct current from the input node to the power rail and collectively cause a total inrush current and corresponding voltage at the power rail to gradually increase.

Abstract translation: 一种装置包括输入节点，为电路负载供电的电力轨道以及在输入节点和电力轨道之间彼此并联耦合的多个电流路径。 每个电流路径分别提供感测输出以指示路径中的电流和具有用于控制路径中的电流的控制输入的电流开关。 控制电路单独地耦合到每个控制输入和单独的每个感测输出，在非零输入电压最初被施加到输入节点之后，基于其中指示的电流来单独地控制每个通路中的电流，使得所有的 路径同时将电流从输入节点传导到电力轨道，并共同引起总浪涌电流和电力轨道上的相应电压逐渐增加。
