NCT3941S TR

Overview

The NCT3941S TR is a fully integrated DC fan motor driver manufactured by Nuvoton Technology Corporation. It utilizes PMOS technology to drive brushed DC motors with an output current of 500mA. The device operates within a supply and load voltage range of 8V to 17.6V. It features a low-side output configuration and accepts on/off interface control signals. The component is housed in an 8-SOIC package with an exposed pad (8-SOP-EP) for surface mount installation, supporting a junction temperature range from -20°C to 125°C.

Feature Summary

Fully integrated driver combining control logic and power stage
PMOS technology for efficient brushed DC motor driving
Low-side output configuration for simple interface control

Applications

Linear fan speed control systems
Brushed DC motor management in electronic equipment
Thermal cooling solutions requiring on/off regulation

Procurement Notes

Verify the specific suffix designation against official Nuvoton documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure the ordering part number matches the exact electrical parameters and pinout configuration required for the target application design.

Selection Notes

Select this component for applications requiring a simple on/off controlled brushed DC motor driver within the 8V to 17.6V voltage range. Consider the 500mA output capability and low-side topology when designing the power stage. Evaluate the thermal performance requirements given the specified junction temperature range and surface mount packaging constraints.

Part Context

This part belongs to the NCT3941 series of linear fan drivers produced by Nuvoton Technology Corporation. It is designed specifically for controlling DC fans in computer and industrial systems. The series provides integrated solutions for fan speed regulation, distinguishing it from discrete driver implementations.
