RT9819

Micro-Power Voltage Detectors

General Description

Features

^zInternally Fixed Threshold 1.2V to 5V in 0.1V Step

The RT9819 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 1.2V to 5V, which covers most digital applications. It

features low supply current of 3μA. The RT9819 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. RT9819 is provided in SC-70-3,

SC-82 and SOT-23-3 packages.
