Pin 1: GND (Ground) Pin 2: MR (Manual Reset) Pin 3: VDD (Power Supply Voltage) Pin 4: RESET (Reset Output) Pin 5: ADJ (Adjustable Threshold Input)

Functional Features

• Monitors power supply voltage and generates a reset signal when voltage drops below the set threshold.
• Adjustable reset threshold allows customization for different system requirements.
• Manual reset input allows for external reset control.
• Low quiescent current consumption minimizes power consumption in battery-powered applications.
• Power-on reset delay ensures stable system operation during power-up.

Advantages and Disadvantages

Advantages

• Wide operating voltage range makes it suitable for a variety of applications.
• Small package size enables space-saving designs.
• Adjustable threshold provides flexibility for different voltage monitoring requirements.
• Low quiescent current consumption prolongs battery life in portable devices.
• High accuracy and reliability ensure consistent performance.

Disadvantages

• Lack of built-in hysteresis may result in potential false triggering in noisy environments.
• Limited number of available alternative models from the same manufacturer.

Working Principles

The LM3880MFX-1AD/NOPB works by continuously monitoring the power supply voltage through the ADJ pin. When the voltage falls below the set threshold, the RESET pin is pulled low, generating a reset signal. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered through the MR pin.
