TC642VUA概述

    # TC642 PWM Fan Speed Controller with FanSense™ Technology
    Product Introduction
    The TC642 is a high-performance PWM fan speed controller specifically designed for brushless DC fans. It provides a sophisticated solution for applications requiring precise temperature-based fan speed regulation, acoustic noise reduction, and prolonged fan life. By utilizing pulse-width modulation (PWM) techniques, the TC642 ensures efficient control of fan operations while offering robust protection against fan failures.
    Key applications include power supplies, personal computers, file servers, telecom equipment, UPS systems, power amplifiers, and general-purpose fan speed control scenarios. The product offers a unique combination of features such as FanSense™ fault detection technology, low-power shutdown mode, and support for NTC/PTC thermistors, making it ideal for modern electronic systems where reliability and efficiency are paramount.
    Technical Parameters
    The following table summarizes the critical technical specifications of the TC642:
    | Parameter | Value | Unit |
    |
    | Supply Voltage | 3.0 to 5.5 | V |
    | Fan Voltage | Independent of supply
    | PWM Frequency | 26 to 34 | Hz |
    | Maximum Supply Current | 1.0 | mA |
    | Shutdown Mode Current | 25 | µA |
    | Input Leakage Current | ±1.0 | µA |
    | Output Low Voltage | ≤0.3 | V |
    | Output High Voltage | ≥80% of VDD
    | Fault Output Threshold | 50 to 90 | mV |
    | Over-Temperature Threshold | 70 | mV |
    Electrical Characteristics
    - Support for External Thermistors: Provides voltage output from 1.25V to 2.65V for 0% to 100% duty cycle.
    - Temperature Range: Operates within -40°C to +125°C.
    - Startup Timer: Ensures reliable fan startup by triggering 32 cycles of PWM at power-on or after fault conditions.
    Product Features and Advantages
    The TC642 offers several standout features that make it highly competitive in its market segment:
    1. Temperature Proportional Control: The PWM function allows precise fan speed adjustments based on ambient temperature, reducing unnecessary energy consumption.
    2. FanSense™ Technology: Detects fan faults, including open/short circuits and blocked airflows, ensuring system reliability and early fault detection.
    3. Efficient Power Management: Supports low-voltage operation (3.0V to 5.5V) and offers a shutdown mode to minimize standby power usage.
    4. Compact Packaging: Available in an 8-pin MSOP package, allowing easy integration into space-constrained designs.
    5. Safety Features: Over-temperature indication and fail-safe mechanisms prevent system overheating and potential thermal runaways.
    Its ability to integrate seamlessly with existing systems and maintain performance under adverse conditions makes it a preferred choice for mission-critical applications.
    Application Cases and Usage Recommendations
    The TC642 is commonly employed in environments where thermal management and noise reduction are critical. Some practical use cases include:
    1. Data Centers: Controlling fan speeds dynamically to balance cooling efficiency and operational costs.
    2. Personal Computing: Optimizing fan noise in laptops and desktops to enhance user experience.
    3. Telecommunications: Ensuring stable performance of equipment in high-density server racks.
    Usage Tips:
    - Use thermistors compatible with the TC642's input voltage range (1.25V to 2.65V) to achieve optimal performance.
    - Connect the FAULT output to an interrupt pin on a microcontrolle
