Key Featrues
200ms Power OK/Reset Time Delay: Ensures a stable power supply before the system resumes operation, preventing erratic behavior during power-up or brownout conditions. This delay improves system stability and reduces the risk of data corruption.
Independent Watchdog Timer: Monitors system activity and triggers a reset if the system becomes unresponsive. This feature enhances system reliability by preventing software lock-ups and ensuring continuous operation.
On-Board Gating of Chip-Enable Signals: Provides precise control over memory access, ensuring data integrity during write cycles. This feature minimizes the risk of data corruption and improves overall system efficiency.
Voltage Monitor for Overvoltage Warning: Detects and alerts when the supply voltage exceeds safe levels, protecting sensitive components from damage. This feature enhances system durability and reduces the risk of hardware failure.
Applications
Nonvolatile Memory Protection: The MAX792/MAX820 is perfect for protecting CMOS RAM, EEPROM, or other memory devices from data corruption during power fluctuations. Its write protection feature and low-line comparator ensure data integrity, making it ideal for applications in data logging, automotive systems, and IoT devices.
Industrial System Watchdog: The MAX792/MAX820 is well-suited for industrial systems requiring robust fault detection and recovery. Its watchdog timer with fault output and pulsed watchdog warning ensures timely system shutdown or recovery in case of software or hardware failures, making it ideal for factory automation and process control systems.
Battery-Free Power Management: The MAX792/MAX820 is ideal for systems without battery backup, providing reliable power-supply monitoring and reset functionality. Its manual-reset input and programmable low-line comparator make it suitable for consumer electronics, medical devices, and portable equipment where power efficiency and reliability are essential.
