Infineon BTM7810K: A High-Performance Motor System IC for Advanced Automotive Applications

The rapid evolution of automotive systems, particularly with the rise of electric and hybrid vehicles, advanced driver-assistance systems (ADAS), and enhanced comfort features, demands highly integrated and robust electronic components. Addressing this need, the Infineon BTM7810K emerges as a premier motor system integrated circuit (IC) engineered to deliver superior performance, reliability, and efficiency in the demanding automotive environment.

This IC represents a significant leap in power electronics integration. It is a highly integrated motor driver system that combines a three-phase MOSFET bridge, a smart driver IC, and comprehensive protection features into a single, compact package. This level of integration drastically reduces the system's footprint on the printed circuit board (PCB), simplifies the design-in process, and enhances overall reliability by minimizing the number of external components and interconnections.

At the core of the BTM7810K's performance is its exceptional power handling capability. Designed to operate with high efficiency, it minimizes power losses and thermal dissipation, which is critical for maintaining performance and longevity in the thermally challenging under-the-hood and body electronics applications. Its low on-state resistance (RDS(on)) ensures that energy is delivered to the motor with minimal waste, contributing to longer driving ranges in electric vehicles and reduced fuel consumption in conventional cars.

Robustness and reliability are paramount for any automotive component. The BTM7810K is built to meet stringent automotive quality standards, typically AEC-Q100 qualified. It incorporates a suite of advanced protection mechanisms, including:

Over-current protection (OCP)

Over-temperature protection (OTP)

Under-voltage lockout (UVLO)

Short-circuit protection

These features safeguard the IC, the motor it controls, and the broader vehicle system from potential damage caused by electrical faults or harsh operating conditions. Furthermore, its design ensures excellent electromagnetic compatibility (EMC), reducing noise emissions and preventing interference with other sensitive electronic systems in the vehicle.

The application scope of the BTM7810K is vast, making it a versatile solution for modern automobiles. It is ideally suited for driving brushless DC (BLDC) motors and permanent magnet synchronous motors (PMSMs), which are ubiquitous in:

Electric power steering (EPS) systems

Electric water and oil pumps

Thermal management fans

Advanced HVAC compressors

Engine cooling fans

Actuation systems for turbochargers, throttle control, and other valves

Its ability to provide smooth and precise motor control contributes to quieter operation, improved vehicle efficiency, and enhanced driver comfort.
