PCS811/PCS812  
5-Pin µP Voltage Supervisor with Manual Reset  
FEATURES  
DESCRIPTION  
PCS811/PCS812 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

Tight Voltage Threshold Tolerance: 1.5%  
Low profile Package: SOT-23-5  
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 PCS811  
and PCS812 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.
