概要

Description

The NCP301LSN30T1G is a voltage detector from ON Semiconductor designed for monitoring power supplies in digital systems. It provides a supervisory function by issuing a reset signal whenever the monitored voltage drops below a pre-defined threshold. This specific model is set for a 3.0V threshold, making it suitable for systems operating around this voltage level.
Key features include low power consumption, typically in the microamp range, which makes it ideal for battery-powered applications. It ensures system stability by preventing erratic behavior in microcontrollers or other digital circuits during undervoltage conditions. The device is housed in a compact SOT-23 package, facilitating space-saving designs.
The NCP301LSN30T1G offers a quick response time and a precise voltage detection threshold with minimal hysteresis. It is widely used in consumer electronics, automotive applications, and any other systems requiring reliable voltage monitoring to protect against power-related issues.

Package

The NCP301LSN30T1G is typically available in a SOT-23 package, which is a small-outline, three-lead transistor package commonly used for surface-mount technology (SMT) circuits.

Pinout

The NCP301LSN30T1G is a voltage detector IC from ON Semiconductor. It typically comes in a 3-pin SOT-23 package. The main function of this device is to monitor the voltage level of a power supply and generate a reset signal when the monitored voltage falls below a specified threshold. This helps ensure that microcontrollers and other digital systems operate correctly by preventing them from operating at low or unstable supply voltages. The device is often used in power-on reset circuits for microcontrollers, battery-powered electronics, and other applications where voltage monitoring is critical.
