Functional Features

• Monitors the voltage level of a power supply in real-time.
• Provides a reset output signal when the voltage falls below the threshold.
• Supports manual reset functionality through the MR pin.
• Low quiescent current ensures minimal power consumption.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows for versatile applications.
• High accuracy ensures precise voltage monitoring.
• Low quiescent current minimizes power consumption.
• Small package size (SOT23-6) enables space-saving designs.

Disadvantages

• Limited threshold voltage options may not suit all applications.
• Lack of built-in hysteresis may result in oscillations near the threshold voltage.

Working Principles

The MAX6385XS24D1-T operates by comparing the input voltage at the TH pin with a fixed internal reference voltage. When the input voltage falls below the threshold, the reset output is activated, indicating a low voltage condition. The MR pin can be used to manually reset the device. The IC operates within the specified supply voltage range and consumes minimal power during operation.
