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.

Unlimited Blocks, Tabs or Accordions with any HTML content can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules.

Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
