The MC33164-3 and MC34164-3 are  
undervoltage sensing circuits designed  
specifically for use as reset controllers in  
microprocessor-based systems. They  
offer the designer an economical, space  
efficient solution for low supply voltage  
detection when used in combination  
with a single pull-up resistor. Adding  
one capacitor offers the functionality of  
a programmable delay time after power  
returns. The MC33164-3 and MC34164-3  
consist of a temperature stable reference  
(V = 2.7V Typ)

   Outputs Fully Defined At V 1V (See  
comparator with hysteresis, high-current  
clamping diode and an open collector  
output stage capable of sinking more  
than 6mA over the full temperature  
range. The MC33164-3 and MC34164-3's
