Pin Configuration

The MAX6388XS37D3-T features a simple three-pin configuration:

• Pin 1 (GND): Ground connection.
• Pin 2 (MR): Active-low reset output.
• Pin 3 (VCC): Power supply input.

Functional Features

• Monitors the voltage level continuously and compares it with the programmed threshold voltage.
• Generates an active-low reset signal when the voltage falls below the threshold.
• Offers an adjustable reset timeout period to accommodate different system requirements.
• Provides a manual reset input for external control of the reset signal.

Advantages and Disadvantages

Advantages: - Compact and space-saving SOT23-3 package. - Wide supply voltage range allows compatibility with various power sources. - Adjustable reset timeout period offers flexibility in system design. - Manual reset input provides additional control options.

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

Working Principles

The MAX6388XS37D3-T operates by continuously monitoring the voltage level at the VCC pin. When the voltage falls below the programmed threshold, the circuit generates an active-low reset signal on the MR pin. The reset signal remains active until the voltage rises above the threshold or the reset timeout period elapses.

Detailed Application Field Plans

The MAX6388XS37D3-T is widely used in various electronic systems that require reliable voltage monitoring and reset functionality. Some common application fields include:

1. Microcontrollers and microprocessors
2. Embedded systems
