A load dump protection system is operable to provide protection for power transistors used to drive a blower motor of a vehicle. The load dump protection system includes circuitry for detecting an over-voltage transient. The circuitry adjusts a drive transistor into a saturation mode in response to a detection of an over-voltage transient. The circuitry lowers the power dissipated by the drive transistor when the drive transistor is in the saturation mode.
