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 supply voltage and keeps the RESET and RESET outputs active (high and low, respectively) as long as the supply voltage has not reached its nominal voltage 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 inactive states. Since the time delay for most microcomputers and microprocessors is in the order of several machine cycles, the device internal time delay is determined by an external capacitor connected to the CT input (pin 3). tpo = 1.3 x 104 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 ext
ernal capacitor (typically 0.1 uF) 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 25oC to 85oC ; the TL7700AC series is characterized from 0oC to 70oC.
