Detailed Pin Configuration

The MAX6385XS23D3-T has three pins:

1. GND: Ground connection.
2. OUT: Output pin that provides an active-low open-drain signal.
3. VCC: Power supply input.

Functional Features

• Monitors the voltage level of a power supply.
• Provides an output signal when the voltage falls below the programmed threshold.
• Active-low open-drain output allows for easy interfacing with other devices.
• Low quiescent current ensures minimal power consumption.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows for versatile applications. - Precise voltage monitoring with low accuracy deviation. - Low-power operation extends battery life. - Small package size enables space-constrained designs.

Disadvantages: - Limited threshold voltage options may not suit all applications. - Active-low open-drain output requires additional pull-up resistor for certain configurations.

Working Principles

The MAX6385XS23D3-T operates by comparing the input voltage (VCC) with the programmed threshold voltage. When VCC falls below the threshold, the output pin (OUT) is pulled low, indicating a power supply fault. The active-low open-drain output allows multiple devices to be connected together, and an external pull-up resistor can be used to achieve the desired logic level.
