| 摘要 | A circuit includes a first node having a first supply voltage, a second node having a second supply voltage, and a voltage detector coupled between the first node and the second node, the voltage detector including a first output node. A clamp circuit is coupled between the first node and the second node. The voltage detector is configured to drive the first output node to the first supply voltage in response to a difference between the first supply voltage and the second supply voltage exceeding a predetermined threshold voltage value. The clamp circuit is configured to establish a conduction path between the first node and the second node in response to the first or second output node being driven to the first supply voltage. | ||
