RT9834

Micro-Power Voltage Detector with Manual Reset

General Description

Features

^Internally Fixed Threshold 1.2V to 5V in 0.1V Step

The RT9834 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 1.2V to 5V, which covers most digital

applications. It features low supply current of 3μA. The

RT9834 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 RT9834 is available in the SC-82 and

SOT-143 packages.

^High Accuracy 1.5%

^Low Supply Current 3μA

^No External Components Required

^Quick Reset within 20μs

^Built-in Recovery Delay : 0ms, 55ms, 220ms, 450ms

Options

^800ns Glitch Immunity of Manual Reset Input

^Low Functional Supply Voltage 0.9V

^CMOS Push-Pull Output

^Small SC-82 and SOT-143 Packages

^RoHS Compliant and Halogen Free

Applications
