1 Understanding Short-to-Ground Events

In a system there are two primary types of short scenarios, enable into short, and a hot short. An enable into short happens when the device is shorted while unpowered and is enabled into a short triggering the current limit protection. A hot short however is when the device is actively applying power to a load and is shorted triggering the current limit protection. The hot short scenario is understood to be the most severe because the device is heated due to the active FET before the short happens. The results in this document come from testing TI high side switches in a hot short.
