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.
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.
RT9808 is N-Channel, open-drain output.
