DesignSpark Circuit Simulator | LED Driver | Thermal Shutdown | Vishay

By Mike Donnelly - Principal Engineer at Siemens Digital Industries Software.

This LED lighting example demonstrates the value of simulating both the electrical and thermal aspects of power dissipating circuits together, simultaneously. In this design, a Vishay NTCLE100 Thermistor (168-0113) is used in a detection circuit to monitor the enclosure temperature. It provides thermal shut-down protection, to keep the enclosure temperature below a specified value.

Please first login to DesignSpark Circuit Simulator (opens in new tab), before trying to edit the design below.
