Working Principles

The MAX16052AUT+T is designed to monitor the supply voltage of a system and generate a reset signal when the voltage falls below a certain threshold. The threshold voltage can be adjusted using an external resistor connected to the TH pin or set to a fixed value. When the monitored voltage drops below the threshold, the active-low RESET# output is asserted, indicating a power failure or low voltage condition. The reset signal remains active until the voltage rises above the threshold or a timeout period elapses. The device also includes a manual reset input and a watchdog timer for added system reliability.
