RT9833

Micro-Power Voltage Detectors with Manual Reset

General Description

Features

^zInternally Fixed Threshold 1V to 5V in 0.1V Step

The RT9833 is a micro-power voltage detector with

deglitched manual reset input supervising the power supply

voltage level for microprocessors (μP) 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 3μA. The

RT9833 performs supervisory function by sending out a

reset signal whenever the V_DDvoltage falls below a preset

threshold level. This reset signal will last the whole period

before V_DDrecovering. Once V_DDrecovered 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_ILlevel. The RT9833 is available in the SC-82 package.
