Pin Configuration

The MAX6388XS46D3-T has a SOT23-3 package with the following pin configuration:

```

---

| | --| VCC GND |-- Pin 1: Ground (GND) --| RESET OUT |-- Pin 2: Reset Output (RESET OUT) --| THRESHOLD |-- Pin 3: Threshold Input (THRESHOLD) |___________| ```

Functional Features

• Monitors the supply voltage and generates a reset signal when it falls below the set threshold.
• Adjustable reset threshold allows customization for different applications.
• Fixed reset timeout period ensures proper system reset.
• Low quiescent current minimizes power consumption.

Advantages and Disadvantages

Advantages: - Precise voltage monitoring ensures reliable system operation. - Adjustable reset threshold provides flexibility for different voltage requirements. - Small package size allows for space-saving designs. - Low quiescent current reduces power consumption.

Disadvantages: - Fixed reset timeout period may not be suitable for all applications. - Limited supply voltage range (1.6V to 5.5V) may restrict compatibility with certain systems.

Working Principles

The MAX6388XS46D3-T operates by continuously monitoring the supply voltage through the THRESHOLD pin. When the voltage falls below the set threshold, the RESET OUT pin generates a reset signal, indicating that the system needs to be reset. The reset signal remains active for a fixed timeout period of 140ms, ensuring proper system reset even if the voltage fluctuates momentarily.
