____ VDD | | ---->| | | | GND | | ---->| | |____| OUT

Pin Description: - VDD: Power supply input - GND: Ground reference - OUT: Open-drain output

Functional Features

• Voltage Monitoring: The NCP301LSN25T1 continuously monitors the input voltage and compares it with the threshold voltage.
• Reset Signal Generation: When the input voltage falls below the threshold, the open-drain output pulls low, generating a reset signal.
• Adjustable Hysteresis: The hysteresis can be adjusted to prevent false triggering and ensure stable operation.

Advantages and Disadvantages

Advantages: - Low quiescent current consumption - Wide operating voltage range - Adjustable hysteresis for improved stability - Small package size for space-constrained applications

Disadvantages: - Limited accuracy of the threshold voltage (±1%)

Working Principles

The NCP301LSN25T1 operates by comparing the input voltage with the internally set threshold voltage. When the input voltage falls below the threshold, the open-drain output is pulled low, generating a reset signal. The adjustable hysteresis ensures that the output remains low until the input voltage rises above a higher threshold, preventing false triggering.

Application Field Plans

The NCP301LSN25T1 finds applications in various fields, including: 1. Power supply monitoring in embedded systems 2. Battery-powered devices 3. Industrial automation 4. Automotive electronics 5. Consumer electronics
