    摘要: An embodiment method for power switch temperature control comprises monitoring a power transistor for a delta-temperature fault, and monitoring the power transistor for an over-temperature fault. If a delta-temperature fault is detected, then the power transistor is commanded to turn off. If an over-temperature fault is detected, then the power transistor is commanded to turn off, and delta-temperature hysteresis cycling is disabled.
