description/ordering information  
The TL7702B, TL7705B, and TL7733B are integrated-circuit supply-voltage supervisors designed for use as  
reset controllers in microcomputer and microprocessor systems. The supply-voltage supervisor monitors the  
supply for undervoltage conditions at the SENSE input. During power up, the RESET output becomes active  
(low) whenV attains a value approaching 1 V. AsV approaches 3 V (assuming that SENSE is aboveV ),

the delay-timer function activates a time delay, after which outputs RESET and RESET go inactive (high and  
low, respectively). When an undervoltage condition occurs during normal operation, outputs RESET and  
RESET go active. To ensure that a complete reset occurs, the reset outputs remain active for a time delay after  
the voltage at the SENSE input exceeds the positive-going threshold value. The time delay is determined by

the value of the external capacitor C : t ≈ 2.6 × 10 × C , where C is in farads (F) and t is in seconds (s).

An external capacitor (typically 0.1 µF) must be connected to REF to reduce the influence of fast transients in  
the supply voltage.  
The TL7702BC, TL7705BC, and TL7733BC are characterized for operation from 0°C to 70°C. The TL7702BI,  
TL7705BI, and TL7733BI are characterized for operation from –40°C to 85°C. The TL7705BQ is characterized  
for operation from –40°C to 125°C. The TL7705BM is characterized for operation from –55°C to 125°C.
