---

| | --| VCC GND |-- Pin 1: Ground (GND) --| MR RST |-- Pin 2: Reset Output (RST) --| TH OUT |-- Pin 3: Threshold Input (TH) --| GND VCC |-- Pin 4: Supply Voltage (VCC) --| RESET GND |-- Pin 5: Ground (GND) |___________| ```

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 a reliable reset signal is generated.
• Low quiescent current minimizes power consumption.

Advantages and Disadvantages

Advantages: - Precise voltage monitoring ensures proper device operation. - Adjustable threshold allows flexibility in different voltage requirements. - Small package size (SOT23-6) saves board space. - Low-power design reduces overall power consumption.

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

Working Principles

The MAX6388XS40D6-T operates by continuously monitoring the supply voltage through the TH pin. When the voltage falls below the set threshold, the internal comparator triggers and generates a reset signal on the RST pin. The reset signal remains active for the fixed timeout period of 140ms, ensuring a reliable reset is provided to the connected device. The adjustable threshold feature allows customization based on specific voltage requirements.
