SUPPLY COLLAPSE DETECTION CIRCUIT |
摘要 |
A supply collapse detection circuit is described. The supply collapse detection circuit includes threshold detection circuitry coupled to a first power supply and to a second power supply that provides a second voltage. The supply collapse detection circuit also includes supply collapse output circuitry coupled to the threshold detection circuitry to receive a detection signal when the second voltage drops. The supply collapse output circuitry includes an output node to provide an output signal indicating the drop. The supply collapse detection circuit additionally includes feedback circuitry coupled to the first power supply, to the threshold detection circuitry and to the supply collapse output circuitry. The feedback circuitry reduces leakage when the second voltage drops.
