The MAX690SCSA+ from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to maintain system integrity during power failures or unexpected events. This device is an essential component for managing system resets and power-on resets to ensure that microprocessors and digital systems power up in a known, stable state every time.

Key Features

• Power Supply Voltage Monitoring: The MAX690SCSA+ monitors the power supply voltage and ensures that the system's microprocessor is reset to a known state during power-up, power-down, and brownout conditions.
• Low Power Consumption: With its low power consumption, this supervisory circuit is ideal for use in power-sensitive applications, ensuring minimal impact on the overall power budget of the system.
• Adjustable Reset Threshold: The device offers an adjustable reset threshold voltage, allowing designers to tailor the reset activation point to specific system requirements.
• Backup Battery Switchover: In the event of a main power failure, the MAX690SCSA+ includes a backup battery switchover feature that enables the system to continue operating from a backup power source without interruption.
• Watchdog Timer: A built-in watchdog timer helps to ensure that the system operates as expected by monitoring the microprocessor activity and initiating a system reset if necessary.
