The RT9819B-15GU3 is a micro-power voltage detector designed for supervising power supply voltage levels in microprocessors and digital systems. It features internally fixed threshold levels ranging from 1.2V to 5V in 0.1V increments, making it suitable for a wide range of digital applications. The device operates with a low supply current of 3OºA and provides a quick reset signal within 20Oºs when the voltage drops below the preset threshold. The reset signal remains active until the voltage recovers, with configurable recovery delay options of 0ms, 55ms, 220ms, and 450ms. The RT9819B-15GU3 is available in multiple package types, including SC-70-3, SOT-23-3, and WDFN-6L 1.6x1.6, and is compliant with RoHS standards. It is suitable for applications in computers, controllers, intelligent instruments, and portable battery-powered equipment. The device's high accuracy of ¬±1.5% and low functional supply voltage of 0.9V enhance its reliability in critical power monitoring scenarios.
