RT9808

Micro-Power Voltage Detectors

General Description

Features

The RT9808 is a micro-power voltage detector

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 1.5V to 5V, which covers most digital

applications. It features low supply current of 3µA.

^zInternally Fixed Threshold 1.5V to 5V in 0.1V Step

2% Accuracy

^zLow Supply Current 3µA

^zQuick Reset within 20µS

^zBuilt-in Recovery Delay 200mS

^zLow Functional Supply Voltage 0.9V

^zN-Channel Open Drain Output

^zSmall 3-Pin SOT-23/SOT89 and 5-Pin SOT-25

Packages

The RT9808 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 up-crossing the threshold level,

the reset signal will be released if VDD is above

threshold and last for the whole period of reset active

time out.
