Abstract
Devices and methods provide a protection device for maintaining a steady output on a gate driver terminal despite fluctuations in a power supply, the protection device including low voltage detection circuitry configured to monitor the power supply and detect fluctuations in the power supply; and gate isolation circuitry configured to isolate the gate driver terminal from the power supply if the low voltage detection circuitry detects a fluctuation in the power supply, wherein a voltage of the gate driver terminal is maintained within a preselected range when the gate is isolated.
