Product Overview: ADM805LAN from Analog Devices Inc.

The ADM805LAN is a sophisticated microprocessor supervisory circuit that ensures reliable system operation through monitoring power supplies in digital systems. Manufactured by Analog Devices Inc., a leader in high-performance semiconductors, this product is designed to provide peace of mind for engineers integrating it into their electronic designs.

Key Features:

• Precision Voltage Monitoring: The ADM805LAN is engineered to monitor the power supply voltage of a microprocessor (µP) or other voltage-sensitive systems. It provides a precise comparison of the supply voltage to a preset threshold level, ensuring that the system operates within safe parameters.
• Power-On Reset Control: Upon detecting a voltage below the acceptable threshold, the ADM805LAN generates a reset signal to the microprocessor. This signal is maintained for approximately 200ms after the supply voltage has risen above the reset threshold, allowing the system to stabilize before normal operation resumes.
• Manual Reset Input: An additional feature is the manual reset capability, which allows for a reset to be triggered with an external pushbutton or logic signal, providing an extra layer of control for system operators.
• Low Power Consumption: The device is optimized for low power consumption, making it suitable for power-sensitive applications. This ensures that the supervisory circuit does not significantly impact the overall power budget of the system it is protecting.

Applications:

The ADM805LAN is versatile and can be used in a wide array of applications including:

• Computers and computer peripherals
• Embedded systems
• Industrial controllers
• Portable battery-powered devices
