```

---

| | --| VDD|-- Pin 1: Power Supply Voltage Input --| GND|-- Pin 2: Ground --| MR |-- Pin 3: Manual Reset Input (Active-Low) --| RST|-- Pin 4: Reset Output --| VTR|-- Pin 5: Voltage Threshold Selection Input |____| ```

Functional Features

1. Voltage Monitoring: The LM8364BALMFX20 continuously monitors the power supply voltage and compares it with the selected threshold voltage.
2. Reset Signal Generation: When the monitored voltage falls below the threshold, the IC generates a reset signal on the RST pin, indicating that the power supply is unstable.
3. Manual Reset: The MR pin allows for manual resetting of the system by pulling it low.
4. Threshold Selection: The VTR pin provides options to select the desired threshold voltage from the available options.

Advantages and Disadvantages

Advantages: - Accurate voltage monitoring and reliable reset generation - Wide operating voltage range - Low quiescent current consumption - Small package size for space-constrained applications

Disadvantages: - Limited number of threshold voltage options - Lack of built-in hysteresis for noise immunity

Working Principles

The LM8364BALMFX20 operates by comparing the power supply voltage with the selected threshold voltage. If the voltage drops below the threshold, the IC generates a reset signal, which can be used to initiate a system reset or perform other necessary actions. The manual reset feature allows for additional control over the system's behavior.

Detailed Application Field Plans

The LM8364BALMFX20 finds applications in various fields where stable operation of digital systems is critical. Some potential application areas include: - Microcontrollers and microprocessors - Embedded systems - Industrial automation - Power management systems - Automotive electronics - Consumer electronics
