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 DS1818 has an open-drain output with an internal 5.5kΩ pull-up resistor for use in a wired-AND circuit. The DS1818 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. * Improves Reliability of Processor Operation * Temperature-Compensated Voltage Monitor for Precise, Automated Power-Fail Detection * Automatically Restarts a Microprocessor After Power Failure * Maintains Reset for 150ms After VCC Returns to Tolerance for Processor Stabilization * Monitors Pushbutton for External Override * Active-Low Reset Output * Efficient Open-Drain Output with Internal 5.5kΩ Pullup Resistor Saves Power and Space * 35µA (max) Quiescent Current * Allows for Easy Design with No Complicated Settings * Fixed 3.3V Reset Threshold * 5%, 10%, and 20% Tolerance Versions Available * Operates in Most Commercial and Industrial Environments * -40°C to +85°C Operating Temperature Range * MXD1818 Offers Improved Performance over the DS1818 https://elecena.pl/product/22301557/3-3v-econoreset-with-pushbutton 2022-12-25 https://elecena.pl/product/22301557/3-3v-econoreset-with-pushbutton 2025-01-20
