Overview

July 14, 2021 GENERAL DESCRIPTION The SP809 is a low power mic roproc essor (μP) supervisory circuit used to monitor power supplies in μP and digital systems.
It provides 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 identify invalid signals, which last less than 140ms.
Low supply current (1μA) makes SP809 ideal for port able equipment.
The SP809 is available in a 3 pin SOT-23 pac kage.
