METHOD OF AND CIRCUIT FOR BROWN-OUT DETECTION |
摘要 |
A circuit and method for detecting a brown-out condition and providing a feed-forward transfer function in a power supply circuit. A comparison circuit is coupled to a delay element through a latch. A second delay element is connected between the first delay element and an input of the latch. The output of the first delay element is connected to a clamping circuit via a logic circuit. A first voltage is compared with a reference voltage to generate a comparison voltage, which is transmitted through the latch and the first delay element. The comparison voltage is monitored at an output of the first delay element. A brown-out condition occurs if the comparison voltage being monitored at the output of the first delay element results from the first voltage being less than the reference voltage. |
