Still troubled by the high-frequency noise of server fans and insufficient heat dissipation efficiency of desktop computers? Traditional drive solutions suffer from loud noise and high heat generation, and their complex sensor structures often lead to a rising failure rate.

Today, Junmin Technology introduces a dedicated BLDC driver IC solution designed specifically for desktop and server cooling fans. It solves core pain points from the root, enabling devices to operate efficiently with stable cooling and ultra-low noise.

Precise matching, covering full-scenario voltage requirements.

To meet the diverse power supply requirements of desktop and server cooling fans, Junmin Technology recommends three three-phase BLDC driver ICs with comprehensive voltage coverage and differentiated functional features, achieving full-scenario adaptation from 5V to 24V.

PT2513B

✅ PT2512 (2.2~8V Sine Wave Drive)

Designed specifically for small fans in 5V power supply systems. It features high integration and minimal peripheral circuits, effectively reducing PCB space occupation, making it an ideal choice for slim devices and small-size fans.

✅ PT2513B (6~16V Sine Wave Drive)

Optimized for mainstream 12V fan applications. Adopting 180° sine wave current control, it greatly reduces electromagnetic noise and torque ripple, enabling smoother fan operation and significantly improving acoustic performance and heat dissipation efficiency.

✅ PT2515 (12~24V Sine Wave + Hall Drive)Supports both sensorless sine wave drive and Hall sensor drive modes to meet the control requirements of different motor solutions. Its 12~24V wide voltage range perfectly covers high-power server fan scenarios, delivering excellent flexibility and reliability.

Core Advantages, Reshaping the New Standard of Fan Drive

✅ Sensorless Drive, Optimized Cost and Reliability

Adopting sensor‑less control technology, no additional Hall sensor installation is required. It not only simplifies the motor structure and reduces material costs, but also eliminates system risks caused by sensor failures, greatly improving long‑term operational stability.

✅ Sine Wave Drive, Say Goodbye to Harsh Noise

Traditional square‑wave drive easily generates high‑frequency electromagnetic noise and torque ripple. The 180° sine wave control technology delivers smoother current output and significantly lowers operating noise, creating a quieter environment for data centers and office spaces.

✅ Multiple Protections, Safeguarding Stable Equipment Operation

Integrated with comprehensive protection mechanisms including soft start, over-current protection, thermal shutdown, and locked-rotor protection. It effectively handles abnormal fan operating conditions, prevents equipment overheating damage caused by drive faults, and builds a solid safety barrier for server and desktop systems.

✅ Highly Integrated Design, Simplifying Development ProcessThe single chip integrates motor control and drive functions with very few peripheral components required. It greatly shortens the product development cycle, reduces PCB design complexity, and enables your cooling fan solution to be launched quickly.
