Abstract:
A method for controlling an efuse circuit is provided. The method includes the following steps. A sample signal of a switch is provided. An error signal is generated according to the sample signal and a reference signal. The error signal is compared with a threshold. A voltage across a control node of the switch and an output node of the switch is clamped to a preset voltage value when the error signal is greater than the threshold.
