Functional Features

1. Voltage Monitoring: The NCP380HMU15AATBG continuously monitors the input voltage and provides a reset signal when it falls below the programmed threshold.
2. Manual Reset: The MR pin allows for manual reset functionality, enabling users to override the reset signal.
3. Adjustable Threshold: The reset threshold voltage can be easily adjusted using external resistors, providing flexibility in different applications.
4. Power-On Reset Delay: It ensures a fixed delay of 150ms before generating the reset signal upon power-up, allowing sufficient time for stable voltage levels.

Advantages and Disadvantages

Advantages

• Low quiescent current makes it suitable for power-sensitive applications.
• Adjustable reset threshold offers flexibility in voltage monitoring.
• Small package size enables space-constrained designs.
• Power-on reset delay ensures stable voltage levels during power-up.

Disadvantages

• Limited operating temperature range (-40°C to +85°C).
• Not suitable for high-voltage applications above 5.5V.

Working Principles

The NCP380HMU15AATBG operates by comparing the input voltage with the programmed threshold voltage. When the input voltage falls below the threshold, the reset output is activated, indicating a low-voltage condition. The power-on reset delay ensures that the reset signal is generated only after a stable voltage level is reached during power-up.

Detailed Application Field Plans

The NCP380HMU15AATBG finds application in various fields, including:

1. Battery-Powered Devices: It is commonly used in portable electronic devices, such as smartphones, tablets, and wearables, to monitor battery voltage and initiate appropriate actions.
2. Industrial Control Systems: The voltage supervisor ensures reliable operation of control systems by monitoring critical voltage levels and triggering necessary resets.
3. Automotive Electronics: It plays a crucial role in automotive applications, monitoring voltage levels in various subsystems and providing reset signals when required.
4. Power Management: The NCP380HMU15AATBG is used in power management circuits to ensure stable voltage supply and protect sensitive components from voltage fluctuations.
