Abstract
A vehicle powertrain includes a monolithically integrated load switch, mirror switch, and temperature array, and a gate driver. The gate driver includes a first comparator configured to filter a current level of the mirror switch, and a second comparator configured to provide a reference to the first comparator based on temperature array output such that a gate discharge rate of the switch, enabled by the first comparator, varies proportionally with a temperature adjusted filtered current level.
