Product Overview: MAX695EWE+T by Maxim Integrated

The MAX695EWE+T is a highly integrated microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with +5V powered circuits.

Key Features

• Voltage Monitoring: This device ensures that the system's voltage levels are under strict surveillance, providing a reset output during power-up, power-down, and brownout conditions.
• Reset Timeout: It features a preset timeout delay which guarantees a proper system reset by holding the reset line low for a minimum of 200ms after VCC has risen above the reset threshold level.
• Watchdog Timer: The integrated watchdog timer with a 1.6s timeout (typical) helps in detecting and recovering from software failures.
• Battery Backup Switching: It includes a battery backup capability that automatically switches to a backup battery when the main power supply drops below a designated threshold, ensuring uninterrupted operation of memory and real-time clocks.
• Chip Enable Gating: The product offers chip enable gating to write-protect memory when VCC is out of tolerance.
• Compact Package: The MAX695EWE+T comes in a 16-SO Wide package, optimized for space-constrained applications.
