SP809 / SP810  
3 Pin Microprocessor Supervisor Circuit  
February 2011  
Rev. 2.0.0  
GENERAL DESCRIPTION  
APPLICATIONS  
The  
SP809/SP810  
are  
low  
power  
Portable Electronic Devices  
Electrical Power Meters  
Digital Still Cameras  
µP Power Monitoring  
microprocessor (μP) supervisory circuits used  
to monitor power supplies in μP and digital  
systems.  
They provide 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.  
FEATURES  
Ultra Low Supply Current 1µA (typ)  
Guaranteed Reset valid to VCC = 0.9V  
140ms Power-On Reset Pulse Width  
Both the SP809 and SP810 were designed with  
a reset comparator to help identify invalid  
signals, which last less than 140ms. The only  
difference between them is that they have an  
active-low RESET output and active-high  
RESET output, respectively. Low supply  
current (1μA) makes SP809/SP810 ideal for  
portable equipment.  
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  
The devices are available in 3 pin SOT-23  
package.
