アプリケーション/用途
説明
The DS1812 (5V) and DS1817 (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 high reset.
The output has a push-structure capable of maintaining a valid output to 0 volts with a 100kΩ pull-down resistor. The low-power circuit has a quiescent current consumption of only 40 micro-amps.
The DS1817 replaces discrete components and saves space, particularly in the new SOT-23 package. EconoResets can benefit any system that requires reliable processor operation, especially consumer products like printers, HVAC, energy management, cellular telephones, PDAs, and set-top boxes.
