Infineon BTM7752G: A High-Performance 180A H-Bridge for Advanced Motor Control Systems

The demand for robust, efficient, and intelligent motor control is accelerating across industries, from automotive electrification and industrial automation to advanced robotics. Meeting this demand requires power modules that deliver exceptional performance, reliability, and integration. The Infineon BTM7752G stands out as a premier solution, a fully integrated 180A H-Bridge designed to set a new benchmark for high-current motor drive applications.

At its core, the BTM7752G is a monolithic, high-current DC motor driver housed in a compact and robust package. Its H-Bridge configuration allows for bidirectional control of a single DC motor, making it ideal for applications requiring precise direction and speed management, such as electric power steering (EPS), hydraulic pumps, starter generators, and heavy-duty industrial actuators.

A defining feature of this module is its remarkable current handling capability, supporting a continuous current of 180A and peak currents even higher. This is achieved through advanced packaging technology and a highly efficient MOSFET-based output stage, which minimizes conduction and switching losses. The result is superior thermal performance and the ability to handle high power loads without external paralleling of discrete components, simplifying design and saving valuable board space.

Beyond raw power, the BTM7752G is engineered for intelligence and resilience. It incorporates a comprehensive suite of integrated protection features that safeguard both the module and the system. These include under-voltage lockout (UVLO), over-current protection (OCP), over-temperature protection (OTP), and short-circuit protection. Such features are critical for maintaining system integrity in harsh operating environments and preventing catastrophic failures.

The module also offers advanced diagnostic capabilities, providing feedback on status and fault conditions. This allows for predictive maintenance and easier system debugging. Furthermore, its compatibility with microcontroller interfaces via a highly efficient PWM input ensures seamless integration into sophisticated digital control systems, enabling precise modulation of speed and torque.
