Abstract
A system including an automated test equipment (ATE) and an interface board. The interface board includes a temperature monitor that compares a sensor temperature to a predetermined temperature. The associated temperature sensor may be located near one or more selected components on the device under test or the interface board. If the sensor temperature exceeds the predetermined temperature the temperature monitor turns off one or more power supplies of the ATE.
Claims20
An apparatus comprising:
- an automated test equipment including a power supply;
- an interface board, communicatively coupled to the automated test equipment, including a temperature monitor, wherein the temperature monitor,
- receives a sensor temperature signal received from a temperature sensor;
- compares a value corresponding to the sensor temperature signal to a predetermined temperature value;
- and
- drives an alert signal to asserted state if the sensor temperature signal value exceeds the predetermined temperature value;
- and
- wherein the alert signal is coupled to the power supply to turn off the power supply when the alert signal is in the asserted state.
The apparatus of claim wherein the temperature sensor is integral to the temperature monitor.
The apparatus of claim 18, wherein the interface board further has a means for further turning of the power supply when a temperature proximate one or more components operating at elevated temperatures or proximate one or more temperature sensitive components on the interface boar or the device under test raises above a threshold temperature.
An apparatus comprising:
- an automated test equipment including a power supply;
- an interface board, communicatively coupling the automated test equipment and to a device under test, wherein the interface board includes a temperature monitor having,
- a means for comparing a value corresponding to a sensor temperature signal received from a temperature sensor to a predetermined temperature value, wherein the temperature sensor is located proximate one or more components operating at elevated temperatures or proximate one or more temperature sensitive components on the interface board or the device under test, and
- a means for turning off the power supply when the sensor temperature signal value exceeds the predetermined temperature value.
