Disadvantages: - Fixed reset threshold voltage - Limited reset timeout period

Working Principles

The MAX16059ATT19+T is a voltage supervisor IC that continuously monitors the supply voltage. When the voltage falls below the preset threshold, it asserts the reset output pin, indicating a power-down or brownout condition. The reset output remains active until the supply voltage rises above the threshold and the reset timeout period elapses. The manual reset input allows for an immediate system reset when triggered.
