High-Current Half-Bridge Motor Drive with Infineon's BTN7933B PROFET™
In modern motor control applications, delivering high current efficiently and reliably is a critical challenge. The half-bridge configuration is widely used in DC motor driving, offering bidirectional control and smooth operation. Infineon’s BTN7933B PROFET™ (Protected FET) emerges as an ideal solution for such demanding scenarios, integrating advanced protection features with high-performance power switching.
The BTN7933B is a high-current half-bridge driver capable of handling continuous currents up to 30 A, making it suitable for automotive and industrial applications such as electric power steering, throttle control, and heavy-duty actuators. Its low on-state resistance (typically 25 mΩ) ensures minimal power dissipation, enhancing overall system efficiency and thermal performance.
A key advantage of the BTN7933B is its comprehensive set of built-in protection mechanisms. These include over-current protection, under-voltage lockout, over-temperature shutdown, and short-circuit protection. Such features significantly improve system robustness and reduce the need for external components, simplifying PCB design and lowering total cost.
Moreover, the device supports PWM (Pulse Width Modulation) frequencies up to 10 kHz, enabling precise speed and torque control of DC motors. The integrated diagnosis feedback pin provides real-time status on fault conditions, facilitating quick debugging and preventive maintenance.
The BTN7933B PROFET™ from Infineon stands out as a highly integrated, protected half-bridge motor driver, offering high current capability, exceptional efficiency, and robust protection—making it an excellent choice for next-generation motor drive systems.
