SP809EK-L-3-1/TR
监控电路 3 Pin Microprocessor Supervisor Circuit RESET
GENERAL DESCRIPTION SP809EK-L-3-1/TR
The SP809/SP810 are low power
microprocessor (μP) supervisory circuits used
to monitor power supplies in μP and digital
systems.
They provide applications with benefits of
circuit reliability and low cost by eliminating
external components. If the VCC supply
voltage falls below preset threshold then a
reset signal is asserted for at least 140ms
after VCC has risen above the reset threshold.
Both the SP809 and SP810 were designed with
a reset comparator to help identify invalid
signals, which last less than 140ms. The only
difference between them is that they have an
active-low RESET output and active-high RESET
output, respectively. Low supply current (1μA)
makes SP809/SP810 ideal for portable
equipment.
