ADM810TART Voltage Supervisor by Analog Devices Inc.

The ADM810TART is a robust voltage supervisor designed to maintain system integrity in the face of unexpected power fluctuations. Manufactured by Analog Devices Inc., a leader in precision high-performance integrated circuits, this device is part of their extensive portfolio of power management solutions.

Key Features

• Reset Output: The ADM810TART provides a reset output during system power-up, power-down, and brownout conditions. This feature ensures that the microprocessor and other sensitive components are reset to a known state during these critical times.
• Voltage Monitoring: It monitors the supply voltage of 3.3V powered systems. If the monitored voltage drops below the factory-set threshold, the reset signal is asserted (active low) to prevent system errors.
• Low Power Consumption: With its low power consumption, the ADM810TART is an ideal choice for power-sensitive applications, contributing to overall energy efficiency.
• Built-in Watchdog Timer: The integrated watchdog timer provides an additional layer of system reliability by periodically checking for system malfunctions and initiating a system reset if necessary.
• Automatic Reset Generation: The device can generate a reset signal for a minimum of 140 ms (typical) after Vcc has risen above the reset threshold level, ensuring ample time for system stabilization.

Applications

The ADM810TART is versatile and can be used in a wide range of applications, including:

• Computers and Servers
• Embedded Systems
• Portable/Battery-Powered Equipment
• Industrial Controllers

Technical Specifications

The device comes in a compact SOT-23 package and operates over a wide temperature range, making it suitable for various environmental conditions. It requires minimal external components, which simplifies design and reduces board space.

Conclusion

With its precision voltage monitoring and low power consumption, the ADM810TART from Analog Devices Inc. is a reliable and efficient solution for system voltage supervision. Its ease of integration and robust feature set make it an excellent choice for designers looking to enhance system reliability in their electronic products.
