RT9802

User Programmable Micro-Power Voltage Detectors

General Description

Features

^zUser Programmable Threshold 1.5V to 5V in 0.1V

The RT9802 is a micro-power voltage detector

supervising the power supply voltage level for

microprocessors (μP) or digital systems. It provides user

programmable threshold levels with 0.1V step ranging

from 1.5V to 5V, which covers most digital applications. It

features low supply current of 3μA. Selection of V_THis

easily achieved through 3 pins connected to GND, V_DDor

floating for different threshold voltage settings. Two versions

of threshold voltages, 1.5V to 4V and 2.5V to 5V, which

are programmed in factory are offered by customer

demands.

Step with ± 3% Accuracy

^zLow Supply Current 3μA

^zQuick Reset within 20μs

^zBuilt-in Recovery Delay 200ms

^zLow Functional Supply Voltage 0.9V

^zSmall SOT-23-6 Package

^zRoHS Compliant and 100% Lead (Pb)-Free

Applications

z Computers

z Controllers

The RT9802 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. Reset signal will release after V_DD

is recovered and lasts for the whole period of ResetActive

Time-out period.
