The RT9818 is a micro-power voltage detector from Richtek that supervises the power supply voltage level for microprocessors (μP) or digital systems. It provides internally fixed threshold levels ranging from 1.2V to 5V with 0.1V per step, which covers most digital applications. It features low supply current of 3μA. The RT9818 performs supervisory function by sending out a reset signal whenever the VDD voltage falls below a preset threshold level. This reset signal will last the whole period before VDD recovering. Once VDD recovered upcrossing the threshold level, the reset signal will be released after a certain delay time. RT9818 is provided in SC-82, SC-70-3, SOT-23-3, SOT-23-5 and SOT-89 packages.
