DS1818R-10+T&R General Description

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.

Key Features

Improves Reliability of Processor Operation
- Temperature-Compensated VoltageMonitor for Precise, Automated Power-Fail Detection
- Automatically Restarts a Microprocessor After Power Failure
- Maintains Reset for 150ms After V_CCReturns 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
