GigaDevice: Launches a New Three-Phase Brushless Motor–Specific Gate Driver
GigaDevice has launched three brand-new models. Three-phase brushless motor-specific gate driver — GD30DR1001, GD30DR1401, and GD30DR1901. These products precisely cover the mainstream 40V, 120V, and 600V voltage platforms. With high integration, robust drive capability, and exceptional reliability, they deliver a one-stop motor‑drive solution for consumer electronics, home appliances, power tools, and industrial equipment. The launch of these new products helps create motor control systems that are more compact, more efficient, and more stable.
Covers multiple voltage platforms, precisely matching application requirements.
As the demands for motor‑control performance continue to rise in smart devices, power tools, and industrial automation, system designers are confronted with mounting challenges in efficiency, reliability, and integration. GigaDevice’s three newly launched analog products all adopt a three‑phase independent half‑bridge architecture, support 3.3V/5V logic inputs, and can directly drive MOSFET or IGBT power devices, thereby simplifying system design while effectively reducing overall BOM costs and development complexity.
GD30DR1001 It is a 40V three-phase gate‑drive IC for driving P‑channel MOSFET power switches, with an operating supply voltage of 5.5 V to 40 V. It is compatible with 3.3 V and 5 V input logic levels and integrates a 5 V LDO capable of delivering 50 mA, providing power to both the internal logic and an external MCU. The chip incorporates multiple protection features, including undervoltage protection and input shoot‑through protection, and includes a built-in 60 ns dead‑time. It is offered in a highly integrated SOP16/QFN16 package. This device is suitable for brushless DC motor applications such as pedestal fans, air purifiers, and small pumps and valves.
GD30DR1401 It is a device that integrates three independent half-bridge gate‑drive chips, specifically designed to drive dual N‑channel high‑voltage MOSFET power transistors or GaN devices. It features a floating offset voltage of +120 V, is compatible with 3.3 V/5 V input logic levels, and incorporates a 5 V LDO with a 100 mA load current as well as a 12 V control circuit. The output current capability is IO+2.0 A / –2.5 A. It also includes built-in safety features such as dead‑time control, undervoltage protection, and shoot‑through prevention. This model is suitable for applications including server fans, consumer drones, power tools, garden equipment, cleaning appliances, and kitchen appliances.
GD30DR1901 It also integrates three independent half-bridge gate‑drive ICs, capable of driving dual N‑channel high‑voltage MOSFET power devices or IGBTs, with a floating offset voltage of +600 V. It is compatible with 3.3 V/5 V input logic levels and features an integrated 5 V LDO delivering up to 50 mA of load current. Built‑in safety protection functions include dead‑time control, undervoltage protection, and shoot‑through prevention. This model is suitable for applications such as personal care appliances, white goods, industrial inverters, high‑voltage fans and pumps, and photovoltaic inverters.
Design advantages that balance integration, reliability, and ease of use
The GD30DR1001, GD30DR1401, and GD30DR1901 series have undergone systematic optimization at both the architectural design and functional integration levels. By integrating key functional modules onto a single chip and incorporating robust protection mechanisms and standardized interfaces, this series not only simplifies system design but also further enhances overall operational stability and development efficiency.
Highly integrated architecture, simplifying system design.
The device integrates an LDO, dead‑time control, and multiple protection features on a single chip; some models even feature a built‑in bootstrap diode, thereby reducing the need for external diodes, discrete resistors, and voltage‑regulation components. This highly integrated design not only lowers BOM costs but also significantly simplifies PCB layout, enhancing system compactness and overall reliability.
Multiple protection mechanisms enhance system robustness.
The device features comprehensive built-in protection functions, including undervoltage lockout (UVLO), shoot-through protection for the power switches, and LDO short‑circuit protection, effectively mitigating potential risks associated with low‑voltage drive and shoot‑through conditions. Coupled with a wide operating temperature range of –40°C to +125°C, it ensures long‑term stable operation under high‑temperature and high‑electromagnetic‑interference conditions, meeting the demands of industrial‑grade applications.
Standardized interface design accelerates system development.
It supports 3.3V/5V logic input interfaces, enabling direct connection to mainstream microcontrollers such as GigaDevice’s GD32 MCU, thereby facilitating the implementation of a complete “MCU + Driver” motor control solution. A standardized interface and drive architecture help lower the design barrier, shorten the development cycle, and accelerate product introduction and mass‑production ramp‑up.
Currently, the GD30DR1001, GD30DR1401, and GD30DR1901 are fully available for sample requests and have entered mass production. The entire product family is packaged in a standard tape-and-reel format, supporting automated manufacturing requirements and helping customers rapidly bring their products to market and seize competitive advantages.
