Working Principles

The MAX6450UT26L+T is a voltage supervisor integrated circuit that continuously monitors the system voltage. When the voltage falls below the threshold set by the TH pin, the RESET output is asserted low, indicating a system reset condition. The reset remains active until the voltage rises above the threshold or a manual reset signal is applied to the MR pin.

The device operates with low quiescent current, making it suitable for power-sensitive applications. It can be powered from a wide supply voltage range, allowing compatibility with various systems. The reset timeout period ensures that the system remains in a reset state long enough for proper initialization.
