---

| | --| VDD | --| GND | --| MR | --| RESET | --| VOUT | |_______| ```

• VDD: Power supply input
• GND: Ground reference
• MR: Manual reset input (active-low)
• RESET: Reset output (active-low)
• VOUT: Output voltage

Functional Features

1. Voltage Monitoring: The NCP380HMU10AATBG continuously monitors the input voltage and provides a reset signal when it falls below the threshold voltage.
2. Adjustable Threshold: The reset threshold voltage can be adjusted to suit specific application requirements.
3. Power-On Reset Delay: The device ensures a stable reset output for a fixed delay time after power-up, allowing sufficient time for the system to stabilize.
4. Push-Pull Output: The reset output is in a push-pull configuration, providing both high and low logic levels.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various systems.
• Low quiescent current minimizes power consumption.
• Adjustable threshold voltage enhances flexibility.
• Small package size enables use in space-constrained applications.

Disadvantages

• Lack of built-in hysteresis may lead to potential noise-related issues.
• Limited number of pins restricts additional functionalities.

Working Principles

The NCP380HMU10AATBG operates by comparing the input voltage with the adjustable threshold voltage. When the input voltage drops below the threshold, the reset output is activated, indicating a power failure or abnormal voltage condition. The push-pull output ensures reliable signaling to the connected circuitry.

Detailed Application Field Plans

The NCP380HMU10AATBG finds applications in various fields, including: 1. Battery-powered devices: Ensures proper shutdown or system reset when battery voltage drops below a certain level. 2. Industrial control systems: Monitors supply voltages to prevent damage to sensitive components during voltage fluctuations. 3. Automotive electronics: Protects critical circuits from voltage variations, ensuring reliable operation. 4. Consumer electronics: Provides voltage supervision for microcontrollers, ensuring system stability.
