1. VDD: Supply voltage input
2. GND: Ground reference
3. RESET: Active low reset output
4. MR: Manual reset input
5. CT: Capacitor connection for reset timeout adjustment

Functional Features

• Voltage monitoring: The NCP380LSN10AAT1G continuously monitors the input voltage and generates a reset signal when it falls below the threshold.
• Adjustable reset timeout: The reset timeout delay can be adjusted to meet specific system requirements.
• Manual reset capability: The MR pin allows for manual reset, overriding the automatic reset function.
• Power-on reset delay: The device ensures a stable reset output during power-up with a fixed delay of 100ms.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows for versatile applications.
• Low quiescent current minimizes power consumption.
• Small package size enables usage in space-constrained designs.
• Adjustable reset timeout provides flexibility in system design.

Disadvantages

• Limited reset threshold voltage range may not suit all applications.
• Lack of integrated watchdog timer limits advanced monitoring capabilities.

Working Principles

The NCP380LSN10AAT1G operates by comparing the input voltage with a preset threshold. When the voltage drops below the threshold, the reset output is activated. The reset remains active until the voltage rises above the threshold or a manual reset is triggered. The reset timeout delay can be adjusted using an external capacitor connected to the CT pin.
