Product Overview: MAX693CJE+ from Maxim Integrated

The MAX693CJE+ is a highly-integrated microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. Manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering, this device provides exceptional reliability and performance for critical system monitoring functions. Its primary objective is to maintain system integrity through various supervisory activities, including reset output during power-up, power-down, and brownout conditions.

Key Features

• Power Supply Monitoring: The MAX693CJE+ ensures that the µP is only operational with a stable power supply. It monitors the power supply voltage and asserts a reset signal to the µP when the supply voltage falls below the precise factory-set reset threshold, preventing erratic system behavior.
• Battery Backup Switching: This device includes an automatic switch-over to backup battery power, ensuring uninterrupted operation in the event of a primary power failure. It also features a write protection mechanism for CMOS RAM, EEPROM, or other memory devices during power failure.
• Low Power Consumption: With its low power consumption, the MAX693CJE+ is suitable for power-sensitive applications. It helps extend battery life in portable devices, making it an energy-efficient choice for system designs.
• Reset Output: The reset output is guaranteed to be in the correct state for VCC down to 1V, which allows for a reliable reset operation throughout the device's operating range.
• Watchdog Timer: A built-in watchdog timer ensures that the µP does not lock-up due to software or hardware failures. The timer can be disabled if not required for certain applications.

Applications

The MAX693CJE+ is versatile and can be used in a wide range of applications, including:

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