Chinese A High-Performance Solution for BLDC and PMSM Motor Applications
In the ever-evolving world of electric motor control, efficiency, integration, and robustness are more critical than ever. At Wuxi Silicon Source Technology Co., Ltd. (SISTC), we’re proud to introduce our 250 V three-phase gate driver with integrated MCU control capability — a powerful solution tailored for BLDC (Brushless DC) and PMSM (Permanent Magnet Synchronous Motor) applications.
This driver is ideal for drones, power tools, fan motors, and electric pumps, delivering exceptional performance and flexibility for engineers developing compact, high-reliability motion control systems.
Key Features of the 250 V Three-Phase Controller
This high-voltage motor controller is designed for demanding environments and provides several critical features:
- Wide Voltage Range: Supports input voltages up to 250 V DC.
- High-Side & Low-Side Gate Drivers: With built-in bootstrap diodes for high-side gate drive.
- Integrated Fault Protection: Includes undervoltage lockout (UVLO), overcurrent protection (OCP), and shoot-through protection.
- Flexible PWM Input: Suitable for both independent and complementary control modes.
- Compact QFN Package: Minimizes PCB footprint and simplifies thermal management.

Built-in Support for Microcontroller Integration
One of the standout features of this controller is its compatibility with external or onboard microcontrollers, enabling intelligent speed, position, and torque control via algorithms such as:
- FOC (Field-Oriented Control) for smooth and efficient torque output
- Six-step trapezoidal control for simpler and faster implementations
- Closed-loop feedback systems using hall-effect or sensorless feedback
This makes it a perfect match for use with ARM Cortex-M0/M3/M4-based MCUs, as well as other motor control MCU platforms.
Applications and Use Cases
This three-phase controller can be seamlessly integrated into a variety of end applications:
- ✈️ Drones & UAVs – High-speed, compact, and robust motor control
- 🔧 Cordless Power Tools – Efficient torque control with minimal size
- 💧 Water and Air Pumps – Quiet, long-life motor operation
