Key Featrues
Precision Voltage Monitoring: The DS1814 and DS1819 MicroMonitors use a precision temperature-compensated reference and comparator circuit to monitor VCC. This ensures accurate detection of out-of-tolerance power conditions, enhancing system reliability by forcing a reset during power anomalies and preventing microprocessor malfunctions.
Pushbutton Reset Control: The 'A' and 'C' versions of the DS1814/DS1819 debounce pushbutton inputs and generate a minimum 140ms reset pulse. This feature simplifies external override operations, improving user control and system recovery during manual interventions.
Watchdog Timer Function: The 'A' and 'B' versions include a watchdog timer that forces a reset if the strobe input does not change state every 1.12 seconds. This ensures the microprocessor remains operational, preventing software lock-ups and enhancing system stability.
Wide Voltage Tolerance: The DS1819 supports a 20% tolerance for 3.0V systems, making it versatile for low-voltage applications. This broad tolerance range increases compatibility with various power supplies, reducing design constraints and improving flexibility in system integration.
Compact SOT-23-5 Package: Both MicroMonitors are available in a low-cost SOT-23-5 package, which saves board space and reduces manufacturing costs. This compact design is ideal for space-constrained applications, enhancing efficiency in both design and production.
