General Description  
The TS809/810 series are microprocessor (µP) supervisory circuit used to monitor the power supplies in µP and  
digital systems. They provide excellent circuit reliability and low cost by eliminating external components and  
adjustments when used with +5V, +3.3V, +3.0V powered circuits. These circuits perform a single function: they assert  
a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least  
140ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply  
voltages are available. The TS809/810 series have push pull outputs. The TS809/809R have an active low RESET  
output, while the TS810/810R has an active high (RESET) output. The reset comparator is designed to ignore fast  
transients on VCC, and the output guaranteed to be in the correct logic state for VCC down to 1V. Low supply correct  
makes the TS809/810 series ideal for use in portable equipment.
