TOOL LIFESPAN PARAMETER DETECTOR

摘要

Aspects of the disclosure can relate to systems or devices for detecting a lifespan parameter of a power transistor of an electronic device. In an embodiment, a device can include a differential probe configured to connect to a first terminal and a second terminal of a power transistor. The device can also include a voltage detector that senses a voltage signal from the differential probe and a controller configured to determine a lifespan parameter of the power transistor based on the voltage signal. In another embodiment, the voltage detector and the controller can be included in an electronic device (e.g., a drilling tool or another downhole tool). In another embodiment, the voltage detector can be in the electronic device, where the electronic device includes an external port that provides a differential voltage signal detected by the voltage detector to an external measurement tool (e.g., oscilloscope or the like).
