```

---

| | --|----|-- VCC --|----|-- GND --|----|-- RESET |____| ```

• VCC: Power supply input pin
• GND: Ground reference pin
• RESET: Output pin for the reset signal

Functional Features

• Accurate monitoring of power supply voltages
• Adjustable reset threshold to suit different applications
• Generates a reset signal when the voltage falls below the set threshold
• Fixed reset timeout period ensures proper system reset
• Low quiescent current for power efficiency

Advantages and Disadvantages

Advantages: - Precise voltage monitoring - Adjustable reset threshold for flexibility - Small package size for space-constrained designs - Low power consumption

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

Working Principles

The MAX6388XS24D3-T operates by continuously monitoring the power supply voltage connected to the VCC pin. It compares the voltage with the set threshold value, which can be adjusted using external resistors. When the voltage falls below the threshold, the RESET pin is pulled low, generating a reset signal. The reset signal remains active for a fixed timeout period of 140ms, ensuring proper system reset.
