Detailed Pin Configuration

The LM8364BALMF45/NOPB has five pins:

1. GND: Ground connection
2. MR: Manual reset input pin
3. VCC: Positive power supply input
4. RESET: Active-low reset output
5. TH: Threshold voltage selection pin

Functional Features

1. Voltage Monitoring: The LM8364BALMF45/NOPB continuously monitors the power supply voltage and compares it with the selected threshold voltage.
2. Reset Generation: When the power supply voltage falls below the threshold voltage, the LM8364BALMF45/NOPB generates an active-low reset signal to initiate a system reset.
3. Manual Reset: The MR pin allows for manual reset capability, enabling external control over the reset function.
4. Selectable Threshold Voltage: The TH pin provides multiple threshold voltage options, allowing flexibility in setting the desired voltage level for triggering the reset signal.
5. Reset Timeout: After the power supply voltage rises above the threshold voltage, the LM8364BALMF45/NOPB maintains the reset signal for a fixed timeout period of 140ms (typical) to ensure stable system operation during power-up.

Advantages and Disadvantages

Advantages: - Provides reliable power-on reset functionality - Low quiescent current consumption - Wide operating temperature range - Small package size for space-constrained applications

Disadvantages: - Limited threshold voltage options - Lack of adjustable reset timeout period

Working Principles

The LM8364BALMF45/NOPB operates by comparing the power supply voltage with the selected threshold voltage. If the voltage drops below the threshold, the IC generates an active-low reset signal. This signal remains active until the voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The LM8364BALMF45/NOPB finds application in various electronic systems where reliable power-on reset functionality is essential. Some potential application fields include: 1. Microcontroller-based systems 2. Microprocessor-based systems 3. Digital communication devices 4. Industrial control systems 5. Automotive electronics
