Abstract: A solid-state circuit protector includes a first power semiconductor device having an ON resistance that increases with increasing temperature and a second power semiconductor device connected in parallel with the first power semiconductor device having an ON resistance that decreases with increasing temperature. During times when abnormally high currents are flowing through the solid-state circuit protector, the second power semiconductor is switched ON so that some or all of the current is diverted through it, thus protecting the first power semiconductor device from being damaged due to overheating. The first power semiconductor device is either switched OFF, allowing it to cool in anticipation of a lighter load, or is configured to remain ON so that it shares the burden of carrying the high current with the parallel-connected second power semiconductor device yet operates cooler and at a lower ON resistance since it is not required to pass the full current.
