RT9817
Micro-Power Voltage Detectors with Manual Reset
General Description
The RT9817 is a micro-power voltage detector with deglitched manual reset input supervising the power www.

com 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 RT9817 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 signa...
