The MAX821UUS+T has a simple three-pin configuration:
Advantages: - Wide supply voltage range enables compatibility with various systems. - Adjustable threshold voltage provides versatility in voltage monitoring applications. - Low power consumption extends battery life in portable devices. - High accuracy ensures reliable voltage monitoring.
Disadvantages: - Limited number of threshold voltage options (100mV steps). - Open-drain output requires an external pull-up resistor for proper operation.
The MAX821UUS+T operates by comparing the input voltage with the user-defined threshold voltage. When the input voltage exceeds the threshold, the output goes low (active-low). Conversely, when the input voltage falls below the threshold, the output remains high impedance. The threshold voltage can be adjusted using external resistors connected to the IN pin.
