Features and Benefits
- Voltage monitor for power-fail detection
- Active low reset
- 150ms pause for stabilization
- Efficient open-drain output with internal 5.5kΩ pull-up resistor
- Maximum quiescent current of 40µA
- Operating ranges:
- 5V with 5%, 10% or 15% tolerance
- -40°C to +85°C
The DS1811 (5V) and DS1816 (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 open-drain output has an internal 5.5kΩ pull-up resistor for use in a wired-AND circuit.
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.
