description
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:

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 0
°C to 70°C. The TL7770I series is characterized for
operation from –40
°C to 85°C.
