Applications

* with benefits of circuit reliability and low cost by eliminating ext ernal 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. The SP809 was designed with a reset comparator to help ident
