DS1812: 5V EconoReset with Active High Push-Pull Output Data Sheet (Rev. 1)11/19/1999113K
Features and Benefits
- Power-fail detection
- Resets system during power transients
- Push-pull active high reset
- 150ms stabilization pause
- Maximum quiescent current of 40µA
- Operating ranges:
- 5V with 5%, 10% or 15% tolerance
- -40°C to +85°C
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 DS1812 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.
