Overview
Preliminary 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 upcrossing 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.
