Working Principles

The MAX708TESA-T operates by continuously monitoring the supply voltage using an internal voltage reference. When the supply voltage falls below the threshold voltage set by the TH pin, the reset output is activated, indicating a low-voltage condition. The reset remains active until the supply voltage rises above the threshold voltage or a manual reset signal is applied to the MR pin.
