SP810, SP809 - 3 Pin Microprocessor Supervisor Circuit

SP810 Description

February 2011 SP809 / SP810 3 Pin Microprocessor Supervisor Circuit Rev.2.0.0 GENERAL .
The SP809/SP810 are low power microprocessor (μP) supervisory circuits used to monitor power supplies in μP and digital systems.

SP810 Features

* Ultra Low Supply Current 1µA (typ)
* Guaranteed Reset valid to VCC = 0.9V
* 140ms Power-On Reset Pulse Width
* Internally Fixed Threshold 2.3V, 2.6V, 2.9V, 3.1V, 4.4V, 4.6V
* 1.5% Voltage Threshold Tolerance
* 3 Pin SOT-23 Package Part Number SP809N

SP810 Applications

* with benefits of circuit reliability and low cost by eliminating external 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. Both the SP809 and SP810 were designed with a reset comparato
