4. MR#: Manual reset input
5. TH: Threshold voltage selection input

Functional Features

• Precision Monitoring: The MAX6318LHUK31CY-T accurately monitors the voltage level of a power supply.
• Low-Power Operation: With a quiescent current of only 1µA, it minimizes power consumption.
• Reset Output: The active-low RESET# pin provides a signal indicating when the monitored voltage falls below the threshold.
• Manual Reset: The MR# pin allows for manual resetting of the device.
• Threshold Selection: The TH pin enables the selection of different threshold voltage options.

Advantages and Disadvantages

Advantages: - High precision voltage monitoring - Low power consumption - Small package size - Wide operating temperature range

Disadvantages: - Limited threshold voltage options - Manual reset capability may not be required in all applications

Working Principles

The MAX6318LHUK31CY-T operates by comparing the input voltage with a reference voltage set by the TH pin. When the input voltage falls below the selected threshold, the RESET# pin is pulled low, indicating a power supply fault. The device continuously monitors the voltage and provides an accurate indication of its status.
