Working Principles

The MAX16086XS27E/V+T operates by continuously monitoring the supply voltage through the TH pin. When the voltage falls below the threshold level, the RESET pin is asserted low, indicating a system reset condition. The reset timeout period can be adjusted using external components connected to the MR pin. During this period, the RESET pin remains low, ensuring proper system initialization. Once the timeout period elapses or the voltage rises above the threshold, the RESET pin returns to its high state.
