Dual Micro-Power Voltage Detectors

General Description

Features

^zHigh Accuracy 1.5%

The RT9828 is a micro-power voltage detector supervising

the power supply voltage level for microprocessors (uP) or

digital systems. It provides internally fixed threshold levels

ranging from 1.2V to 5V, which covers most digital

applications. It features low supply current of 6uA. The

RT9828 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 the V_DDexceeds the threshold

level, the reset signal will be released after a certain delay

time. The RT9828 is available in SOT-23-6 package.

^zLow Supply Current 6uA
