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) when VCC attains a value approaching 1 V. As VCC approaches 3 V (assuming that SENSE is above VT+),
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 CT: td ≈ 2.6 × 104 × CT, where CT is in farads (F) and td is in seconds (s).
An external capacitor (typically 0.1
F) 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.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
The TL7705BM is obsolete
and no longer is supplied.
