Package: SOT-23-5

Essence: The LM8364BALMF30/NOPB is a voltage supervisor IC designed to monitor the power supply voltage and generate a reset signal when the voltage drops below a specific threshold. It is widely used in various electronic devices to ensure stable and reliable operation.

Packaging/Quantity: The LM8364BALMF30/NOPB is available in a small SOT-23-5 package. It is typically sold in reels containing a specified quantity of ICs.

Specifications

• Supply Voltage Range: 1.6V to 6.0V
• Reset Threshold Voltage: 3.0V
• Reset Timeout Period: 200ms
• Quiescent Current: 10µA (typical)
• Operating Temperature Range: -40°C to +85°C

Pin Configuration

The LM8364BALMF30/NOPB has a total of five pins:

1. GND: Ground connection
2. MR: Manual reset input pin
3. VDD: Positive supply voltage input
4. RESET: Output reset signal
5. TH: Threshold voltage adjustment pin

Functional Features

1. Voltage Monitoring: The LM8364BALMF30/NOPB continuously monitors the power supply voltage and compares it with the preset threshold voltage.
2. Reset Signal Generation: When the monitored voltage falls below the threshold, the IC generates a reset signal on the RESET pin, indicating that the power supply is insufficient.
3. Manual Reset: The MR pin allows for manual reset input, enabling external control over the reset function.
4. Adjustable Threshold Voltage: The TH pin provides the ability to adjust the threshold voltage according to specific system requirements.

Advantages and Disadvantages

Advantages: - Compact SOT-23-5 package for space-constrained applications - Low quiescent current consumption - Wide operating temperature range - Adjustable threshold voltage for flexibility

Disadvantages: - Fixed reset timeout period may not suit all applications - Limited number of pins for additional functionalities

Working Principles

The LM8364BALMF30/NOPB operates by comparing the power supply voltage with the preset threshold voltage. When the voltage drops below the threshold, the IC triggers the reset signal, indicating a power failure or brownout condition. The reset signal remains active until the voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The LM8364BALMF30/NOPB finds extensive use in various electronic systems where reliable power-on reset functionality is crucial. Some common application fields include:

1. Microcontrollers and Microprocessors: Ensures proper initialization and prevents erratic behavior during power-up or voltage fluctuations.
2. Embedded Systems: Provides stable operation and protects critical data during power interruptions.
3. Industrial Control Systems: Safeguards against power supply disruptions and ensures controlled shutdowns during fault conditions.
4. Automotive Electronics: Protects sensitive components from voltage variations and ensures reliable system startup.
