An apparatus that includes a module for use in installing a heatsink, the module comprising a fastener, a first indicator member comprising a first visual indicator surface, and a second indicator member comprising a second visual indicator surface, the first and second indicator members defining an opening for receiving the fastener. The first visual indicator surface is visible when the fastener is not fully installed and the second visual indicator surface is visible when the fastener is fully installed. A method for installing the heatsink with the module is also disclosed herein.

Heatsink with visual installation indicator

In one embodiment, an apparatus includes a module for use in installing a heatsink, the module comprising a fastener, a first indicator member comprising a first visual indicator surface, and a second indicator member comprising a second visual indicator surface, the first and second indicator members defining an opening for receiving the fastener. The first visual indicator surface is visible when the fastener is not fully installed and the second visual indicator surface is visible when the fastener is fully installed. A method for installing the heatsink with the module is also disclosed herein.

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.
