Systems, methods, and devices to protect electronics of a downhole device from overheating in high-temperature wells are provided. In one example, a method includes, while a downhole device is disposed in a wellbore, providing power to first electronics of the downhole device through a switch and providing power to switch control circuitry that controls the switch. The switch may be disposed on a first substrate and the switch control circuitry may be disposed on a second substrate. The method may also include receiving a measurement of a temperature of the downhole device and, when the temperature exceeds a threshold, using the switch control circuitry to open the switch to prevent power from being provided to the first electronics of the downhole device |
