Overview
The ADM6713RAKSZ-REEL7, produced by Analog Devices Inc., is a supervisory circuit designed for use in microprocessor-based systems. It functions as a reset generator, providing a reset signal during power-up, power-down, and whenever the supply voltage falls below a preset threshold. This component is part of the ADM6711/ADM6713 series, which offers various reset threshold options to monitor different supply voltages (2.5 V, 3 V, 3.3 V, and 5 V). The ADM6713 features an open-drain RESET output, a debounced manual reset input, and power supply glitch immunity, making it highly reliable and suitable for low-power portable applications.
