GENERAL DESCRIPTION
The SP 809/SP810 are low power microprocessor (μP) supervisory circuits used to moni tor power supplies in μP and digital s ystems. They provide applications with benefits of circuit reliability and low cost by eliminating external component s. If the VCC supply voltage falls belo w preset threshold then a reset signal is asserted for at least 140ms after VC C has risen above the reset threshold. Both the SP809 and SP810 were designed with a reset comparator to help identif y invalid signals, which last less than 140ms. The only difference between the m is that they h . |
