ON Semiconductor NCP301HSN22T1G Voltage Detector

The ON Semiconductor NCP301HSN22T1G is a high-performance voltage detector designed to provide a reliable solution for systems that require precise voltage monitoring. This voltage detector is part of ON Semiconductor's broad portfolio of power management devices, known for their quality and efficiency. The NCP301HSN22T1G is specifically engineered to detect and respond to under-voltage conditions, ensuring that electronic systems remain within their safe operating parameters.

The device operates by monitoring the voltage level of a power supply or a voltage reference. When the input voltage drops below a factory-programmed threshold, the NCP301HSN22T1G asserts a reset signal, which remains active until the voltage recovers above the threshold, plus a hysteresis margin. This reset signal can be used to reset microcontrollers or other digital systems, preventing improper operation due to low voltage conditions.

Key features of the NCP301HSN22T1G include:

• Factory-Programmed Threshold: The voltage threshold is preset at 2.2V, which is suitable for a variety of low-voltage applications.
• Low Power Consumption: This device is designed for battery-powered applications, with a quiescent current of typically 3 µA, contributing to extended battery life.
• High Accuracy: The voltage threshold accuracy is ±1.5%, providing precise monitoring and protection for sensitive electronics.
• Fast Response Time: The device responds quickly to under-voltage conditions, with a typical response time of 20 µs, ensuring timely corrective actions.
• Open Drain Output: The reset output is an open-drain configuration, allowing for flexible interfacing with other logic levels and the ability to wire-OR multiple devices.
• Temperature Range: The NCP301HSN22T1G operates over a wide temperature range, from -40°C to +125°C, making it suitable for harsh environments.
• Compact Package: The voltage detector is available in a space-saving 5-pin TSOP package, ideal for applications where board space is at a premium.

This voltage detector is an excellent choice for a wide range of applications, including microprocessor/microcontroller systems, portable/battery-powered equipment, and industrial controllers. With its high level of integration and performance, the NCP301HSN22T1G helps ensure the stability and reliability of electronic systems across various sectors.
