• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The NCP301LSN30T1G has three pins:

1. VDD: This pin is connected to the power supply voltage.
2. GND: This pin is connected to the ground.
3. RESET: This pin outputs a low signal when the monitored voltage falls below the threshold.

Functional Features

• Under-voltage detection: The NCP301LSN30T1G monitors the input voltage and triggers an output signal when it falls below the set threshold.
• Adjustable threshold: The threshold voltage can be adjusted within a specified range to suit different applications.
• Low power consumption: The device operates with low quiescent current, minimizing power consumption.
• Fast response time: The NCP301LSN30T1G quickly detects voltage variations and provides a timely output signal.

Advantages and Disadvantages

• Adjustable threshold voltage
• Small package size

Disadvantages

• Limited to under-voltage detection only
• Not suitable for over-voltage protection

Working Principles

The NCP301LSN30T1G works based on a voltage comparator circuit. It compares the input voltage with the set threshold voltage. When the input voltage falls below the threshold, the output pin is pulled low, indicating an under-voltage condition.

Detailed Application Field Plans

The NCP301LSN30T1G finds applications in various fields, including:

1. Power supply monitoring: It can be used to monitor the voltage levels in power supplies and trigger appropriate actions in case of under-voltage conditions.
2. Battery-powered devices: The device can ensure proper battery management by detecting low battery voltage and initiating necessary actions.
3. Industrial control systems: It can be employed in industrial control systems to monitor critical voltage levels and prevent malfunctions.
