Working Principles

The MAX16083AXR46B/V+T operates by continuously monitoring the power supply voltage connected to the VCC pin. When the voltage falls below the user-defined threshold set using the TH pin, the IC generates a reset signal on the RESET pin. This reset signal remains active until the voltage rises above the threshold again or a manual reset is triggered through the MR pin.

During power-up, the IC includes a power-on reset delay to ensure stable operation before releasing the reset signal. This delay prevents premature activation of the reset output during power fluctuations or transients.
