Product Summary
The RT9818C-29GV is a micro-power voltage detector supervising the power supply voltage level for microprocessors (μP) or digital systems. The RT9818C-29GV provides internally fixed threshold levels with 0.1V per step ranging from 1.2V to 5V, which covers most digital applications. The RT9818C-29GV features low supply current of 3μA. The RT9818C-29GV 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. The RT9818C-29GV is provided in SC-82, SC-70-3, SOT-23-3, SOT-23-5 and SOT-89 packages.
