Abstract
Systems and methods for early-onset electrical fault detection are described in which a rate-of-rise of channel current in a device such as a transistor is sensed, indicating whether an electrical fault is present. In some embodiments, the rate-of-rise of the channel current may be sensed by detecting whether a current flowing away from a control terminal of the device is greater than a threshold level. In the event that an electrical fault is detected, the device may be shut off to prevent damage to the device.
