IT809 －
Micro-Power Voltage Detector
Description
The IT809 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 2.67V, 3.0V, 3.3V and
4V which cover most digital applications. It features low supply
current of 10μA. The IT809 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 after a certain delay time. IT809 is
provided in SOT-23-3 packages.
