Working Principles

The MAX6385XS27D1-T operates by comparing the input voltage with the threshold voltage set by the user using the TH pin. When the input voltage falls below the threshold, the RESET# output goes low, indicating a reset condition. Conversely, when the input voltage rises above the threshold, the RESET# output goes high, indicating a normal operating condition. The MR# pin allows for manual resetting of the device.
