Dual Svs, 12V & Pgmmable W/Pgmmable Time Delay

The TL7770 is an integrated-circuit system supervisor designed for use as a reset controller in microcomputer and Microprocessor power-supply systems. This device contains two independent supply-voltage supervisors that monitor the supplies for overvoltage and undervoltage conditions at the VSO and VSU terminals, respectively. When VCC attains the minimum voltage of 1 V during power up, the RESET output becomes active (low). As VCC approaches 3.5 V, the time-delay function activates, latching RESET and RESET active (high and low, respectively) for a time delay (td) after system voltages have achieved normal levels. Above VCC = 3.5 V, taking RESIN low activates the time-delay function during normal system-voltage levels. To ensure that the microcomputer system has reset, the outputs remain active until the voltage at VSU exceeds the threshold value, VIT+, for a time delay, which is determined by an external Timing capacitor such that: td 20 103 capacitance
where td is in seconds and capacitance is in farads.
The overvoltage-detection circuit is programmable for a wide range of designs. During an overvoltage condition, an internal silicon-controlled Rectifier (SCR) is triggered, providing 250-mA peak instantaneous current and 25-mA continuous current to the SCR Gate drive terminal, which CAN drive an external high-current SCR Gate or an overvoltage-warning circuit.
The TL7770C series is characterized for operation from 0C to 70C. The TL7770I series is characterized for operation from -40C to 85C.
