Geehy Launches New GHD3440 Motor Gate Driver to Expand Product Line
The gate driver serves as a critical buffer between low-voltage controllers and high-power circuits. It amplifies control signals, enhancing the efficiency of power device switching. As smart electronic devices proliferate, the demand for gate drivers is increasing, with the market expected to reach $2.7 billion by 2027, according to Yole Group.
Expanding Geehy's Motor Control Solutions
Responding to motor control market demands, Geehy has launched the GHD3440 motor-specific gate driver, following the release of the APM32F035 MCUs.
Key Features
Comprehensive Safety Functions: Supports over-voltage protection, under-voltage protection, shoot-through prevention, and dead-time protection.
High Integration: Reduces system costs with high system integration.
Strong Driving Capability: Offers robust driving capability, minimizing system switching losses and heat generation.
Designed as a three-phase mid-voltage high-speed gate driver IC, the GHD3440 is ideal for driving dual N-channel VDMOS power transistors or IGBTs in bridge circuits, supporting various battery-powered brushless DC motor applications.
Efficiency and Power Optimization
The GHD3440 excels in driving capability and response time, enabling precise input signal response and load change management. This improves motor efficiency and allows for high-precision, high-speed, and low-power motor control, enhancing the development experience.
Available in TSSOP20 and QFN24 packages, the GHD3440 saves board space, reduces material costs, and boosts system reliability.
