RT9828 Dual Micro-Power Voltage Detectors General Description 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 VDD voltage falls below a preset threshold level.
This reset signal will last the whole period before VDD recovering.
Once the VDD exceeds the threshold level, the reset signal will be released after a certain delay time.
The RT9828 is available in SOT-23-6 package.
