Abstract: Provided is a method for producing hydrophobic silica aerogel granules and hydrophobic silica aerogel granules produced thereby, the hydrophobic silica aerogel granules having a suppressed level of specific surface area deterioration and scattering properties. In the method for producing the hydrophobic silica aerogel granules, surface modification, gelation, and solvent substitution can be simultaneously performed in one step, thereby decreasing production time and increasing productivity. Also, by adjusting the addition amount of a non-polar organic solvent when proceeding with a reaction, hydrophobic silica aerogel granules with suppressed scattering properties can be produced. In addition, the hydrophobic silica aerogel granules are silica aerogel particles induced to agglomerate with each other through physical bonding, so that there is an advantage in that the granules can be easily changed into a powder form, thereby having excellent industrial applicability.

Abstract: An electronic circuit includes an output generator and an over-voltage detector. The output generator is configured to output an output signal to an output terminal. In response to an amplitude of a voltage of the output terminal being greater than an allowable amplitude, the over-voltage detector is configured to output an over-voltage detection signal of a first logic value, such that elements included in the output generator are turned off. In response to the over-voltage detector outputting the over-voltage detection signal of the first logic value again before a reference time elapses after the first logic value of the over-voltage detection signal changes to a second logic value of the over-voltage detection signal, the turned-off elements remain turned off. In response to the over-voltage detector outputting the over-voltage detection signal of the second logic value during the reference time, the turned-off elements are turned on.
