basicInfoDescription
basicInfoImageSwitcher
The RT9833 is a micro-power voltage detector with deglitched manual reset input supervising the power supply voltage level for microprocessors (&mu;P) or digital systems. It provides internally fixed threshold levels with 0.1V per step ranging from 1V to 5V, which covers most digital applications. It features low supply current of 3&mu;A. The RT9833 performs supervisory function by sending out a reset signal whenever the V<sub>DD</sub> voltage falls below a preset threshold level. This reset signal will last the whole period before V<sub>DD</sub> recovering. Once V<sub>DD</sub> recovered upcrossing the threshold level, the reset signal will be released after a certain delay time. To pull reset signal low manually, just pull the manual reset input (MR) below the specified V<sub>IL</sub> level. The RT9833 is available in the SC-82 package.
