The CAT812SEUS-T provides a cost-effective solution for ensuring the reliable operation of microprocessor-based systems. The internal reset timeout delay ensures that the microprocessor remains in a reset state long enough to properly initialize after a power-up or brownout event. The active-low reset output is compatible with most microprocessors. The device consumes very little supply current, making it suitable for battery-powered applications. The CAT812SEUS-T is packaged in a small SOT-23, which helps minimize board space. It is commonly used in microcontroller applications that require a means of ensuring reliable start-up following unexpected power drops.
