The RT9819D-43GV 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 supply voltage drops below the preset threshold. The reset signal remains active until the voltage recovers, with a built-in recovery delay option available in various timeout periods, including 450ms for this specific part number. The RT9819D-43GV is available in multiple package types, including SC-70-3, SOT-23-3, and WDFN-6L 1.6x1.6, facilitating integration into compact designs. It is RoHS compliant and suitable for both Pb-free and SnPb soldering processes. This product is particularly applicable in computers, controllers, intelligent instruments, and battery-powered equipment, making it a versatile choice for engineers looking for reliable voltage supervision solutions.
