PCS809/PCS810  
3-Pin µP Voltage Supervisor  
DESCRIPTION  
FEATURES  
Ultra Low Supply Current 1µA(typ.)  
PCS809/PCS810 are low-power 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.  
Guaranteed Reset Valid to VCC=0.9V  
Available in three Output Types: Open Drain  
Active Low (PCS809N), Push-Pull Active Low  
(PCS809), Push-Pull Active High (PCS810)  
140ms Min. Power-On Reset Pulse Width  
Internally Fixed Threshold 2.3V, 2.6V, 2.9V,  
3.1V, 4.0V, 4.4V, and 4.6V  
These devices perform as valid singles in applications with  
VCC ranging from 6.0V down to 0.9V. The reset signal  
lasts for a minimum period of 140ms whenever VCC  
supply voltage falls below preset threshold. Both PCS809  
and PCS810 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.  
Tight Voltage Threshold Tolerance: 1.5%  
Low profile Package: SOT-23-3  
APPLICATIONS  
Notebook Computers  
Digital Still Cameras  
PDAs  
Critical Microprocessor Monitoring  
Low supply current (1µA) makes PCS809/PCS810 ideal  
for portable equipment. The devices are available in 3-  
SOT-23 package
