Key Featrues
Precision Voltage Monitoring: Ensures accurate monitoring of the power supply voltage at 4.65V (or 4.40V for specific models), enhancing system reliability by triggering reset actions during power anomalies, thereby protecting sensitive components and preventing data corruption.
Power OK/Reset Time Delay: Offers configurable reset time delays (50ms, 200ms, or adjustable), allowing flexibility in system design to ensure stable power-up sequences and reduce false resets, improving overall system stability.
Watchdog Timer: Includes a watchdog timer with adjustable intervals (100ms, 1.6s, or customizable), which monitors system activity and initiates a reset if the system fails to respond, ensuring continuous operation and preventing system hangs.
Battery Backup Power Switching: Seamlessly switches to battery backup during power failures, maintaining uninterrupted operation of critical components like CMOS RAM or microprocessors, thereby enhancing system uptime and data integrity.
Low Power Consumption in Standby Mode: Operates with a standby current of just 1µA in battery backup mode, significantly extending battery life and making it ideal for low-power applications or portable devices.

Applications
Microprocessor Reset and Backup Control: The MAX690 family is ideal for providing a reliable reset output during power-up, power-down, and brownout conditions in microprocessor systems. Its integrated battery backup switching ensures seamless operation for CMOS RAM, CMOS microprocessors, or other low-power logic, making it suitable for critical applications in embedded systems and industrial controls.
Watchdog Timer for System Reliability: The MAX690 family includes a watchdog timer that generates a reset pulse if the timer is not toggled within a specified time. This feature enhances system reliability by preventing software lock-ups or malfunctions, making it ideal for use in automotive, medical, and industrial automation systems.
Power Fail Warning and Low Battery Detection: With its 1.3V threshold detector, the MAX690 family is perfect for power fail warning, low battery detection, or monitoring power supplies other than +5V. This capability ensures timely alerts and system shutdowns in portable devices, battery-powered equipment, and backup power systems.
CMOS RAM Write Protection: The MAX690 family provides onboard gating of chip enable signals to protect against erroneous data written to CMOS RAM during low VCC events. This feature is essential for maintaining data integrity in memory-critical applications such as data loggers, point-of-sale systems, and embedded controllers.
