3 Description

The TL7702B, TL7705B, and TL7733B are integratedcircuit

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. When an undervoltage

condition occurs during normal operation, outputs

RESET and RESET go active.

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.
