LM3880MFX-1AA/NOPB

The LM3880MFX-1AA/NOPB is a voltage supervisor integrated circuit (IC) manufactured by Texas Instruments. It is designed to monitor power supply voltages and provide a reset signal to microcontrollers and other digital devices when the supply voltage falls below a specified threshold. This ensures that the system operates reliably and prevents erratic behavior during power fluctuations.

Key Features:

1. Voltage Monitoring: The LM3880 monitors the supply voltage and generates a reset signal when the voltage drops below a predetermined threshold. This is crucial for maintaining the integrity of digital circuits.

2. Adjustable Reset Threshold: The reset threshold can be set using external resistors, allowing for flexibility in different applications. This feature enables designers to tailor the reset voltage to their specific requirements.

3. Active Low Reset Output: The reset output is active low, meaning it goes low when the monitored voltage is below the threshold. This output can be directly connected to the reset pins of microcontrollers or other digital devices.

4. Fast Response Time: The LM3880 has a fast response time, ensuring that the reset signal is generated quickly when the supply voltage drops, which helps in minimizing the risk of system malfunction.

5. Low Quiescent Current: The device operates with low quiescent current, making it suitable for battery-powered applications where power efficiency is critical.

6. Temperature Range: The LM3880 is designed to operate over a wide temperature range, making it suitable for various environmental conditions.

7. Small Package Size: The LM3880MFX-1AA/NOPB comes in a compact MFP (Micro-Fine Pitch) package, which is ideal for space-constrained applications.

8. No External Components Required: The device can function without the need for additional external components, simplifying the design process and reducing overall system cost.

Applications:

• Microcontroller Reset Circuits
• Power Supply Monitoring
• Automotive Electronics
• Consumer Electronics
• Industrial Control Systems

Electrical Characteristics:

• Supply Voltage Range: Typically operates from 1.5V to 5.5V.
