Description and Introduction

Voltage Detector Series with Programmable Delay The **NCP302LSN47T1** is a high-performance voltage detector designed for precision monitoring in electronic circuits. This integrated circuit (IC) is part of ON Semiconductor’s voltage supervisor family, offering reliable power management for applications requiring stable voltage thresholds.  

Featuring a fixed detection threshold of **4.7V**, the NCP302LSN47T1 ensures accurate monitoring of power supply voltages, triggering a reset signal if the voltage falls below the specified level. Its low quiescent current makes it suitable for battery-powered and energy-efficient devices, minimizing power consumption during operation.  

The device operates over a wide voltage range and includes built-in hysteresis to prevent false triggering due to voltage fluctuations. Available in a compact **SOT-23-3** package, it is ideal for space-constrained designs such as embedded systems, IoT devices, and consumer electronics.  

Key features include a fast response time, high accuracy, and robust performance under varying environmental conditions. Engineers often integrate the NCP302LSN47T1 into power management circuits to enhance system reliability by preventing malfunctions caused by unstable voltage conditions.  

With its dependable performance and industry-standard specifications, this voltage detector is a practical choice for applications demanding precise voltage supervision and fault protection.

Alternative Part Number

  • MC33464H-47CT1 --: Voltage supervisor with similar 4.7V threshold and reset function, from ON Semiconductor (successor of Motorola), suitable drop-in for monitoring applications.
  • MAX809SQ47T1 --: 3-pin microprocessor reset supervisor with comparable 4.7V trip point and active-low reset, widely used as a functional replacement.
  • APX803L-47SA-7 --: Low-power voltage detector with 4.7V threshold in SOT-23 package, offering similar reset timing and pinout compatibility.
  • MAX809REUR+T --: Voltage supervisor with 4.7V-class reset threshold in a small SOT-23 package, functionally similar to the NCP302 voltage detector.
  • MCP131T-475E/TO --: 4.75V voltage detector with active-low reset output, comparable threshold and function to the original supervisor IC.
