Functional Features

• Accurate voltage monitoring: The MAX6388XS21D6-T provides precise monitoring of the supply voltage, ensuring reliable operation of the system.
• Reset generation: It generates an active-low reset signal when the monitored voltage falls below the threshold voltage, allowing the system to reset and recover from abnormal conditions.
• Adjustable threshold voltage: The TH pin allows users to select the desired threshold voltage according to their specific application requirements.
• Reset timeout adjustment: The CT pin enables the adjustment of the reset timeout period, allowing customization based on system needs.

Advantages and Disadvantages

Advantages: - Low-power consumption - Wide supply voltage range - Multiple threshold voltage options - Adjustable reset timeout period - Small package size for space-constrained applications

Disadvantages: - Limited number of threshold voltage options - No built-in hysteresis for voltage monitoring

Working Principles

The MAX6388XS21D6-T operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the selected threshold voltage, the IC generates an active-low reset signal. This signal remains active until the voltage rises above the threshold voltage and the reset timeout period elapses.
