The RT9818C-44GV 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 built-in recovery delay options of 0ms, 55ms, 220ms, and 450ms. The RT9818C-44GV is available in multiple package types, including SC-70-3, SOT-23-3, SOT-23-5, and SOT-89, allowing for flexibility in design. 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 portable battery-powered equipment, making it a versatile choice for engineers looking for reliable voltage supervision solutions.
