“The TL7700A series are monolithic integrated circuit supply voltage supervisors specifically desi-gned for use as reset controllers in microcomputer and mi-croprocessor 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 delay that delays the return of the reset output 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 time delay is determined by an external capacitor connected to theCTinput (pin 3).
