Overview of Gate Driver Technology
Gate drivers are essential components in power electronics systems, providing the necessary voltage and current to switch IGBT and SiC power devices. Bronze Technologies offers a comprehensive portfolio of gate driver products including driver cores, single module drivers, multi-module drivers, isolated driver chips, and low-side driver chips for various power levels and applications.
The gate driver sits between the control circuit and the power semiconductor device, providing signal amplification, electrical isolation, and protection functions. Proper gate driver design is critical for achieving optimal switching performance, minimizing losses, and ensuring system reliability.
Driver Cores
Driver cores are plug-and-play gate driver modules designed for high-power IGBT and SiC devices. They integrate isolation, amplification, and protection circuits in a compact form factor. The following table lists available driver core products:
| Model | Package | Max Voltage (V) | Peak Current (A) | Max Frequency (kHz) |
|---|---|---|---|---|
| 2QD30A17K-I-xx | 60kHz | |||
| 2QD0225T12xx-3L | 20kHz | |||
| 2QD0435T17-C | 100kHz | |||
| 2QD0108T17-C-xx | 50kHz | |||
| 2QD0535T33-C-xx | 100kHz |
Driver cores support various power device packages including 62mm, EconoDual, PrimePack, and XHP. They feature integrated short-circuit protection, adjustable gate resistors, and fiber optic signal interfaces for high-noise environments.
Single Module Drivers
Single module drivers are designed for individual IGBT or SiC power modules. They support packages such as IHM, LV100, EconoDual, PrimePack, XHP, and press-pack configurations. These drivers provide plug-and-play functionality with integrated isolation and protection.

Key Design Considerations
When selecting a gate driver, several key parameters must be considered:
- Maximum power device voltage rating – must match or exceed the application requirement
- Gate drive peak current – determines switching speed and loss
- Isolation voltage – ensures safety between control and power circuits
- Switching frequency – affects efficiency and thermal design
- Protection features – short circuit, over-temperature, and under-voltage lockout
- Package compatibility – must match the power module footprint
