---

| | --| VCC GND |-- Pin 1: Ground (GND) --| MR RST |-- Pin 2: Reset Output (RST) --| TH VCC |-- Pin 3: Supply Voltage (VCC) --| CT GND |-- Pin 4: Capacitor Terminal (CT) --| TR GND |-- Pin 5: Transistor Terminal (TR) --| RESET GND |-- Pin 6: Ground (GND) |___________| ```

Functional Features

• Monitors the supply voltage and generates a reset signal when the voltage drops below the set threshold.
• Provides an adjustable reset timeout period to ensure proper system reset.
• Low-power consumption for energy-efficient applications.
• Precision voltage monitoring with various threshold voltage options.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows for versatile applications. - Adjustable reset timeout period provides flexibility in system design. - Small package size (SOT-23-6) enables space-saving designs. - Low-power consumption extends battery life in portable devices.

Disadvantages: - Limited threshold voltage options may not suit all voltage monitoring requirements. - Not suitable for high-voltage applications due to the maximum supply voltage limitation.

Working Principles

The MAX6364LUT46+T operates by continuously monitoring the supply voltage connected to the VCC 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 until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The MAX6364LUT46+T is commonly used in various applications where reliable voltage monitoring and system reset functionality are required. Some typical application fields include:

1. Battery-Powered Devices: Ensures proper operation and prevents data loss by resetting the system when the battery voltage drops below a critical level.
2. Microcontroller Systems: Provides a reset signal to restart the microcontroller when the power supply becomes unstable or fails.
3. Industrial Control Systems: Monitors the power supply voltage in industrial control systems to prevent malfunctions and ensure safe operation.
4. Automotive Electronics: Protects sensitive electronic components by resetting the system when the vehicle's battery voltage drops below a certain threshold.
