Geehy Launches New GHD3440 Motor Gate Driver to Expand Product Line

时间： 2024-06-15 来源：Geehy Semiconductor Official Website

技术问答

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.

GHD3440 Specifications

Input voltage range: 5.5V to 18V, compatible with 3.3V/5V input logic, floating supply offset voltage of +200V.

Built-in VCC/VBS under-voltage lockout (UVLO) for safe power transistor operation.

Shoot-through prevention and 250ns dead-time protection to safeguard power devices.

Embedded pull-down resistors for stable output signals and enhanced driving capability.

High DV/DT noise suppression to ensure performance and prevent interference.

Peak output current: 0.8A@12V, load rise time: 90ns on 3.3nF, peak input current: 1.0A@12V, load fall time: 60ns on 3.3nF.

Operating temperature: -40℃ to +105℃ for stable performance in harsh conditions.

Applications

Power Tools: Electric wrenches, screwdrivers, drills, hammers.

Garden Tools: Lawn mowers, pruners, hedge trimmers, chainsaws.

Cleaning Tools: Electric cleaning brushes, vacuum cleaners.

Geehy continues to innovate with advanced, reliable, and cost-effective solutions for the motor control market. Our lineup includes the GHD3440R Motor Gate Driver with an integrated LDO, the APM32M3514 MCUs with a 200V 6N pre-driver, and the GHD3125R 3P+3N three-phase motor gate driver. These drivers support motor drivers, DC-DC converters, DC-AC inverters, and Class D power amplifiers, providing robust performance for high-demand electronic applications.
