```

---

| | --| VCC GND |-- Pin 1: Ground (GND) --| MR RST |-- Pin 2: Reset Output (RST) --| TH VCC |-- Pin 3: Supply Voltage (VCC) --| GND GND |-- Pin 4: Ground (GND) --| TR GND |-- Pin 5: Threshold Input (TH) --| RESET GND |-- Pin 6: Manual Reset Input (MR) |___________| ```

Functional Features

• Monitors the power supply voltage and generates a reset signal when the voltage drops below the user-defined threshold.
• Adjustable reset threshold allows customization for different voltage levels.
• Provides a manual reset input for immediate system reset.
• Low quiescent current ensures minimal power consumption.

Advantages and Disadvantages

Advantages: - Precise voltage monitoring helps prevent system malfunctions due to low supply voltage. - Adjustable reset threshold accommodates various voltage requirements. - Small package size enables space-saving designs. - Low-power operation prolongs battery life in portable devices.

Disadvantages: - Fixed reset timeout period may not be suitable for all applications. - Limited supply voltage range restricts usage in certain systems.

Working Principles

The MAX6388XS22D6-T operates by continuously monitoring the supply voltage connected to the VCC pin. When the voltage falls below the user-defined threshold set using the TH pin, the circuit triggers a reset signal on the RST pin. This signal remains active until the supply voltage rises above the threshold or a manual reset is applied through the MR pin.
