The TL7700Aseriesaremonolithicintegratedcircuit supplyvoltagesupervisorsspecifically desi-gnedfor 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 .
ycles, the device internal time delay is determined by an external time delay is determined by an external capacitor connected to the CT input (pin 3). td = 1.3 x 104 x CT Where : CT is in farads (F) and td 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 externalcapacitor(typically0.1 µF) 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 TL.
The TL77xxA family of integrated-circuit supplyvoltage supervisors is designed specifically for use as reset controllers.
