MIC809-5  
Microprocessor Reset Circuits  
General Description  
Features  
The MIC809-5 is a power supply supervisor that provides  
under-voltage monitoring and power-on reset generation in  
an industry standard 3-pin SOT package and pinout. The  
reset output is asserted at power-on and any time the input  
voltage drops below the programmed threshold. It remains  
asserted for 30ms (min.) after the input subsequently rises  
back above the threshold boundary. The MIC809-5 has an  
active-low reset output. Hysteresis is included to prevent  
chattering due to noise, and the MIC809-5 is inherently  
immune to brief power supply transients. Typical supply  
current is a low 6µA. For those applications that require a  
manual reset function, see the MIC811/812. For those appli-  
cations that require a longer reset timeout, see the  
MIC809/810. (The MIC809-5 is identical to the industry-  
standardMIC809withtheexceptionofashorterresettimout.)
