The SP809/SP810 are low power microprocessor (
μ
P) supervisory circuits used to monitor
power supplies in
μ
P and digital systems. They provide applications with benefits of circuit
reliability and low cost by eliminating external components. If the V
supply voltage falls below
preset threshold then a reset signal is asserted for at least 140ms after V
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 (1
μ
A) makes SP809/SP810 ideal for portable equipment. The devices are available in
3 pin SOT-23 package.
