Abstract
A remote diode temperature sensing circuit for use in a burn-in system to sense a temperature of a semiconductor device under test includes a temperature sense circuit and an adapter circuit. The temperature sense circuit is configured to output temperature sense currents (I) during a temperature sense routine. The adapter circuit is configured to drive mirrored sense currents (I), which mirror the temperature sense currents, through a diode of the semiconductor device that is connected to an input/output package pin, and present voltage differences across the diode responsive to the mirrored sense currents to the temperature sense circuit. The temperature sense circuit is configured to discharge a temperature output signal that is indicative of the temperature of the diode based on the voltage differences.
