DESCRIPTION
The TL7700A series are monolithic supply voltage
supervisor IC’s specifically designed for use as reset
controllers in microcomputer and microprocessor
systems. During power-up the device tests the sup-
ply voltage and keeps the RESET and RESET out-
puts active (high and low, respectively) as long as
the supply voltage has not reached its nominal volt-
age value. Taking RESIN low has the same effect.
To ensure that the microcomputer system has reset,
the TL7700A then initiates an internal time count
that delays the return of the reset outputs to their in-
active states. Since the time delay for most micro-
computers and microprocessors is in the order of
several machine cycles, the device internal time de-
lay is determined by an external capacitor con-
nected to the CT input (pin 3).
tpo = 1.3 x 10
4 x CT
Where : CT is in farads (F) and tpo in seconds (s). In
addition, when the supply voltage drops below the
nominal value, the outputs will be active until the
supply voltage returns to the nominal value. An ex-
ternal capacitor (typically 0.1
F) must be connected
to the REF output (pin 1) to reduce the influence of
fast transients in the supply voltage.
The TL7700AI series is characterized for operation
from – 25
oC to 85oC ; the TL7700AC series is char-
acterized from 0
oC to 70oC.
