3 Pin Microprocessor Supervisor Circuit

 

 

 

Part Number SP810
Description 3 Pin Microprocessor Supervisor Circuit
Feature November 2017 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 .
