The ADM811RARTZ is a robust voltage supervisor integrated circuit (IC) designed and manufactured by Analog Devices Inc., a leader in the semiconductor industry. This precision voltage monitoring device is engineered to ensure the reliable operation of microprocessor (µP) systems by providing an active low reset signal whenever the monitored power supply voltage falls below a preset threshold.

Key Features

• Voltage Threshold Precision: The device offers tight threshold accuracy, which is critical for sensitive electronic systems, ensuring that the reset signal is triggered exactly when the voltage drops below the specific level.
• Low Power Consumption: With its low power requirements, the ADM811RARTZ is an excellent choice for battery-operated and portable devices, helping to extend their operational lifespan.
• Reset Timeout Delay: The IC features a built-in delay timer that provides a reset signal for a minimum of 140 ms (typical) after the voltage level returns above the threshold, ensuring system stability during transient conditions.
• Watchdog Timer: A watchdog timer is integrated to monitor the microprocessor activity and initiate a system reset if the µP becomes unresponsive, enhancing the overall system reliability.
• Manual Reset Input: The ADM811RARTZ includes a manual reset input, allowing for an external trigger to reset the system, which is useful for debugging and testing purposes.
• Temperature Range: The device is operational over an industrial temperature range, making it suitable for harsh environments.

Applications

The ADM811RARTZ is versatile and can be used in a wide array of applications such as:

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