The MAX6834FXRD3-T from Maxim Integrated is a highly reliable, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a significant level of system reliability through its ability to reset a µP during power-up, power-down, and brownout conditions.

Key Features

• Power Supply Monitoring: This device ensures that the µP is held in reset until the system's power supply reaches a stable and safe operating voltage, and it continues to monitor the supply voltage during operation, resetting the processor if it drops below a preset threshold.
• Low Power Consumption: With its low power consumption, the MAX6834FXRD3-T is ideal for use in portable and battery-operated applications. It helps to extend battery life and reduce overall power usage.
• High Accuracy Reset: The reset threshold voltage is factory-trimmed to high accuracy, which enables the device to provide a reliable reset operation without the need for external components.
• Manual Reset Input: A manual reset input is provided, allowing the user to trigger a reset with an external pushbutton or logic signal.
• Multiple Package Options: The MAX6834FXRD3-T is available in a compact SOT23 package, making it suitable for space-constrained applications.
