应用/用途

描述

The DS1813 (5V) and DS1818 (3.3V) EconoResets are simple three-pin voltage monitors and power-on resets that hold reset for 150ms for stabilization after power returns to tolerance. The voltage monitor uses precision temperature reference and comparator circuits that detect out-of-tolerance conditions and generate an active low reset.

The DS1813 (like the DS1811) has an open-drain output with an internal 5.5kΩ pull-up resistor for use in a wired-AND circuit. The DS1813 also monitors a pushbutton on the reset output, generating a reset when the pushbutton is released.

EconoResets replace discrete components and save space, particularly in the new SOT-23 package. They can benefit any system that requires reliable processor operation, especially consumer products like printers, HVAC, energy management, cellular telephones, PDAs, and set-top boxes.
