The ADM696AR is a robust power supply supervisor designed by Analog Devices Inc., intended to enhance the reliability and extend the operational lifespan of microprocessor (μP) systems. By monitoring the power supply line, it ensures that the μP and associated circuitry are reset during power-up, power-down, and brownout conditions.

Key Features:

• Power Monitoring: The ADM696AR actively monitors the supply voltage and initiates a reset to the μP whenever it detects an out-of-tolerance condition, thus safeguarding the system against erratic behavior.
• Reset Timeout: It features an adjustable reset timeout period that can be set by the user according to the specific needs of the application, providing flexibility and control over the reset sequence.
• Battery Backup Switching: This device includes an automatic battery backup switching function that seamlessly transitions to a backup battery when main power is lost, ensuring uninterrupted operation of vital system components.
• Watchdog Timer: A built-in watchdog timer improves system reliability by resetting the μP if it fails to strobe within a preset time frame, indicative of a system malfunction or software error.
• Low Power Consumption: Designed with power efficiency in mind, the ADM696AR operates with a low quiescent current, making it suitable for power-sensitive applications.
• Wide Operating Temperature Range: It is capable of functioning over a broad temperature range, accommodating various environmental conditions that may be encountered in industrial applications.

Applications:

The ADM696AR is versatile and can be employed in a wide array of applications, including:

• Microprocessor systems
• Computers and servers
• Embedded systems
• Industrial controllers
• Portable/battery-powered equipment

With its comprehensive set of features, the ADM696AR from Analog Devices Inc. is an essential component for maintaining system integrity and ensuring that electronic devices operate reliably under various power conditions.
