  2. TRIP: Output pin that goes low when the monitored voltage falls below the threshold.
  3. SET: Input pin used to set the desired threshold voltage.
  4. VCC: Power supply input for the IC.

Functional Features

  • Monitors the voltage level and provides a digital output indicating if the voltage is above or below the set threshold.
  • Adjustable threshold voltage allows customization for different applications.
  • Low quiescent current makes it suitable for battery-powered devices.
  • Built-in hysteresis prevents output oscillation near the threshold voltage.

Advantages and Disadvantages

Advantages: - Wide supply voltage range enables use in various systems. - Adjustable threshold voltage provides flexibility. - Low quiescent current prolongs battery life. - Small package size saves board space. - Hysteresis ensures stable operation.

Disadvantages: - Limited number of threshold voltage options (100mV steps). - Not suitable for high-voltage applications (>6.0V).

Working Principles

The MAX6385XS44D2-T operates by comparing the input voltage at the SET pin with the internally generated reference voltage. When the input voltage falls below the set threshold, the TRIP pin goes low, indicating a voltage fault. The adjustable threshold voltage is set using an external resistor divider connected to the SET pin.
