Detailed Pin Configuration

The MAX6388XS21D1-T has a total of five pins:

1. VCC: Power supply input pin
2. GND: Ground reference pin
3. MR: Manual reset input pin
4. RESET: Active-low reset output pin
5. TH: Threshold adjust pin

Functional Features

• Monitors the power supply voltage and generates a reset signal when the voltage falls below the set threshold.
• Provides an adjustable reset threshold to accommodate different system requirements.
• Offers a manual reset input for immediate system reset.
• Allows the selection of fixed or adjustable reset timeout periods.
• Low quiescent current consumption ensures minimal power usage.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with various systems. - Adjustable reset threshold provides flexibility in different applications. - Small package size enables space-saving designs. - Low quiescent current consumption reduces power consumption.

Disadvantages: - Lack of built-in hysteresis may result in potential noise-related issues. - Limited number of pins restricts the availability of additional features.

Working Principles

The MAX6388XS21D1-T operates by continuously monitoring the voltage at the VCC pin. When the voltage falls below the set threshold, the RESET pin is pulled low, indicating a system reset condition. The threshold can be adjusted using an external resistor connected to the TH pin. The reset timeout period can also be fixed or adjusted using an external capacitor.
