TML393S /TML393microprocessor (µP) supervisory circuits reduce the complexity and number of components     required to monitor +3V power-supply levels in +3V to     +5V µP systems . These devices significantly improve     system reliability and accuracy compared to separate     ICs or discrete components.

The TML393S/TML393  supervi-

sory circuits provide the following four functions:

1)   A reset output during power-up, power-down, and brownout conditions.

2)   An independent watchdog output that goes low if the watchdog input has not been toggled within 1.6s.

3)   A 1.25V threshold detector for power-fail warning, low-battery detection, or for monitoring a power supply other than the main supply.

4)   An active-low, manual-reset input.

The only difference  between the TML393S  , TML393S/TML393  is the reset-threshold

voltage levels, which are , 2 .93V, and 3 .08V,             respectively . All have active-low reset output signals . The TML393S  are identical to the TML393 ,

except the reset output signal is active-high. The watch- dog timer function for the TML393S/TML393  dis-       ables when the WDI input is left open or connected to a high-impedance state of a low-leakage tri-state output.
