Functional Features

• Accurate voltage monitoring: The MAX16083AXR17O+T continuously monitors the supply voltage and compares it with the selected threshold voltage.
• Reset signal generation: When the monitored voltage falls below the threshold, the MAX16083AXR17O+T asserts an active-low reset signal.
• Adjustable reset timeout: The reset timeout period can be adjusted using an external capacitor connected to the CT pin.
• Manual reset option: The MR pin allows for manual assertion of the reset signal.

Advantages and Disadvantages

Advantages

• Low-power consumption: The MAX16083AXR17O+T operates with low quiescent current, making it suitable for battery-powered applications.
• Precision voltage monitoring: The IC provides accurate voltage monitoring, ensuring reliable system operation.
• Small package size: The 6-pin SOT23 package offers space-saving benefits in compact designs.

Disadvantages

• Limited threshold voltage options: The available threshold voltage options may not cover all voltage requirements of different systems.
• Lack of built-in hysteresis: The MAX16083AXR17O+T does not include built-in hysteresis, which may be required in certain applications to prevent oscillations near the threshold voltage.

Working Principles

The MAX16083AXR17O+T utilizes a voltage comparator to continuously monitor the supply voltage. When the voltage falls below the selected threshold voltage, the comparator triggers the generation of an active-low reset signal. The reset timeout period can be adjusted using an external capacitor connected to the CT pin. The MR pin allows for manual assertion of the reset signal.
