Working Principles

The MAX6836VXSD3+T operates by continuously monitoring the supply voltage connected to the VCC pin. When the voltage falls below the threshold voltage set by the TH pin, the IC generates an active-low reset signal on the RESET pin. The reset signal remains active until the supply voltage rises above the threshold voltage or a manual reset is applied to the MR pin.

The threshold voltage and reset timeout period can be adjusted using external resistors and capacitors connected to the TH and CT pins, respectively. This allows customization of the monitoring parameters based on specific system requirements.
