会社ブログについて Mingjiada Supplies DRV8300: 100V Three-phase BLDC Gate Driver (For Drone and Robot Applications)

Mingjiada supplies DRV8300: 100V three-phase gate driver specifications, parameters, and application scenarios. Comprehensive analysis.

I. Product Overview
The DRV8300 is a 100V three-phase half-bridge gate driver from Texas Instruments designed to drive high-side and low-side N-channel power MOSFETs. The device integrates three independent half-bridge gate drivers that generate the appropriate gate drive voltage for the high-side MOSFET via an integrated bootstrap diode (DRV8300D version) or an external bootstrap diode (DRV8300N version), while the GVDD provides the gate drive voltage for the low-side MOSFET.

With its compact QFN and TSSOP packaging, powerful drive capabilities, and comprehensive protection mechanisms, the DRV8300 is a cost-effective choice for three-phase brushless DC motors (BLDC) and permanent magnet synchronous motors (PMSM) drive solutions. Shenzhen Mingjiada Electronics Co., Ltd., as a globally renowned authorized independent distributor of electronic components, has long and stably supplied Texas Instruments DRV8300 series gate driver chips, providing customers with original product guarantees and fast delivery services.

II. Core Specifications
2.1 Electrical characteristics
Device type: 100V three-phase half-bridge gate driver
Driver: N-channel MOSFET (NMOS)
Gate driver power supply (GVDD): 5V ~ 20V
MOSFET Power Supply (SHx): Support up to 100V
Peak pull current: 750mA
Peak supply current: 1.5A
Bootstrap Architecture: Integrated Bootstrap Diode (DRV8300D)
Logic input support: 3.3V and 5V (absolute maximum 20V)
Propagation delay matching: typical value 4ns
Absolute maximum BSTx voltage: 125V
SHx pin transient negative voltage: up to -22V
SHx pin leakage current: less than 55µA

The DRV8300's gate driver architecture supports up to 750mA peak pull current and 1.5A sink current, ensuring that power MOSFETs complete switching in a very short time, effectively reducing switching losses and improving system efficiency.

2.2 Protection and functional characteristics
The DRV8300 has multiple built-in protection mechanisms, including BST Undervoltage Lock (BSTUV) and GVDD Undervoltage Lock (GVDDUV), providing comprehensive undervoltage protection for both low-side and high-side drives. The device also has a built-in transconductance protection function, effectively preventing the risk of short circuits caused by the simultaneous conduction of the upper and lower tubes of the same bridge arm.

In terms of dead time control, the QFN package model can flexibly adjust the dead time via the DT pin, while the TSSOP package model has a fixed 200ns dead time. Smaller propagation delay and delay matching parameters can minimize dead time requirements, thereby further improving motor drive efficiency.

2.3 Packaging and working conditions
The DRV8300 series offers two compact surface mount packages: a 24-lead QFN package (4×4mm, 0.5mm pin spacing) and a 20-lead TSSOP package (body size 6.5×4.4mm, 0.65mm pin spacing). The operating temperature range is -40°C to +125°C, meeting the temperature requirements of the vast majority of industrial environments and automotive electronics applications.

III. Detailed explanation of application scenarios
The DRV8300 series is suitable for a wide range of three-phase motor drive applications. The following are the main application areas:

3.1 Electric Mobility Field
The DRV8300 is ideally suited for electric bicycle applications. Its compact package size, high transient tolerance, and anti-through features make the system design simpler and more reliable. In electric mobility devices such as electric scooters, electric scooters, and electric vehicles, the DRV8300 can drive motor systems up to 48V, providing efficient and stable power control for mobility devices.

3.2 Drones and Robots
In the fields of drones and multirotor aircraft, the DRV8300 helps customers reduce circuit board footprint and costs without sacrificing performance, thanks to its small package size and high-performance drive capabilities. This device is also suitable for applications requiring precision motor control, such as industrial robots, logistics robots, and RC remote-controlled toys.

3.3 Industrial Automation and Servo Drive
In the field of industrial automation, the DRV8300 is widely used in equipment such as fans, pumps, and servo drives. Its current detection function provides the hardware foundation for closed-loop control. Integrated chip design simplifies the design complexity of three-phase motor drive circuits, enabling engineers to achieve high-performance motor control schemes with fewer peripheral components.

3.4 Power tools and household appliances
The DRV8300 is also suitable for cordless garden power tools, lawnmowers, cordless vacuum cleaners, and other equipment, as well as home appliance scenarios such as inverter air conditioner compressor drives and washing machine motor drives. The device supports applications powered by up to 15 series batteries, making it ideal for portable battery-powered power tools.
