Product Overview: MAX697CWE+ from Maxim Integrated

The MAX697CWE+ is a highly integrated microprocessor (µP) supervisory circuit designed by Maxim Integrated to provide reliable monitoring and control for microprocessor systems. This precision device is engineered to enhance system stability by monitoring power supplies and system activity, ensuring that the µP and associated digital systems operate correctly.

Key Features

• Voltage Monitoring: The MAX697CWE+ includes a precision voltage monitor that keeps a watchful eye on the power supply, ensuring that the µP is reset to a known state during power-up, power-down, and brownout conditions.
• Power-On Reset: It features a power-on reset control which holds the µP in reset for a minimum of 140ms after the power supply has reached its valid level, allowing the system to stabilize before operation begins.
• Watchdog Timer: A built-in watchdog timer serves as a system service monitor, which can be set by an external capacitor to offer a versatile timing range. This helps in detecting and recovering from software failures.
• Backup Battery Switchover: In the event of a power failure, the MAX697CWE+ automatically switches to a backup battery to maintain uninterrupted power supply to the µP and volatile memory.
• Low Power Consumption: Designed with energy efficiency in mind, it operates with low power consumption, making it suitable for battery-powered applications.
• Package: The device is available in a 16-pin wide-body SO package, offering a compact solution for space-constrained applications.

Applications

The MAX697CWE+ is versatile and can be used across various applications that require reliable µP supervision. It is ideal for:

• Computers and Controllers
• Embedded Systems
• Portable/Battery-Powered Equipment
• Intelligent Instruments
• Automotive Systems

With its robust feature set, the MAX697CWE+ is an excellent choice for system designers looking for a comprehensive supervisory solution to safeguard their digital systems from power instabilities and system errors.
