| | --| |-- |____| ```

Pin 1: GND (Ground) Pin 2: VDD (Supply Voltage) Pin 3: MR (Manual Reset Input) Pin 4: RESET (Reset Output) Pin 5: NC (No Connection)

Functional Features

• Voltage monitoring: The NCP380LMUAJAATBG continuously monitors the supply voltage and provides a reset signal when it falls below a certain threshold.
• Manual reset input: The MR pin allows for manual reset control, enabling the user to override the automatic reset function.
• Open-drain output: The RESET pin provides an open-drain output that can be connected to other devices for system-level reset coordination.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows for compatibility with various electronic circuits.
• Low quiescent current minimizes power consumption.
• Adjustable reset threshold voltage provides flexibility in voltage monitoring.
• Small package size enables space-saving designs.
• RoHS compliance ensures environmental friendliness.

Disadvantages

• Limited number of pins may restrict the functionality in complex systems.
• Lack of built-in hysteresis may result in potential oscillations near the threshold voltage.

Working Principles

The NCP380LMUAJAATBG operates by comparing the supply voltage with a preset threshold. When the supply voltage drops below the threshold, the internal circuitry triggers a reset signal on the RESET pin. This signal remains active until the supply voltage rises above the threshold or a manual reset is initiated through the MR pin.

Application Field Plans

The NCP380LMUAJAATBG finds applications in various fields, including: 1. Power management systems 2. Battery-powered devices 3. Microcontrollers and microprocessors 4. Industrial automation 5. Automotive electronics 6. Consumer electronics
