Pin 1: GND (Ground) Pin 2: VDD (Supply Voltage) Pin 3: MR (Manual Reset) Pin 4: RESET (Reset Output) Pin 5: VOUT (Voltage Monitor Output)

Functional Features

1. Voltage Monitoring: The NCP380LMU05AATBG continuously monitors the input voltage and compares it with the user-adjustable threshold voltage.
2. Reset Generation: When the input voltage falls below the threshold, the device generates a reset signal to ensure proper system operation.
3. Manual Reset: The MR pin allows for manual reset control, enabling system restart when required.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows for versatile applications.
• Low quiescent current minimizes power consumption.
• Adjustable reset threshold voltage provides flexibility.
• Small package size enables space-saving designs.
• RoHS compliance ensures environmental friendliness.

Disadvantages

• Limited number of pins may restrict functionality in complex systems.
• Lack of built-in hysteresis may lead to potential noise-related issues.

Working Principles

The NCP380LMU05AATBG operates by comparing the input voltage with the user-defined threshold voltage. If the input voltage drops below this threshold, the device triggers a reset signal, which can be used to initiate system recovery or shutdown procedures. The manual reset feature allows for additional control over the reset function.

Detailed Application Field Plans

The NCP380LMU05AATBG finds extensive application in various electronic systems, including but not limited to: - Microcontrollers - Power management units - Battery-powered devices - Industrial automation systems - Automotive electronics
