Abstract

In applications where high currents are being controlled it is often desirable to use acurrent-sensing FET(SENSEFET* FET) to both control the current and monitor the load current. There is a simple circuit which will protect the SENSEFET FET from damage due to overtemperature which takes advantage of the SENSEFET FET's changing characteristics with increasing temperature.
