Infineon BTN7970BAUMA1 High-Current Half-Bridge Motor Driver IC

The Infineon BTN7970BAUMA1 is a high-performance, integrated half-bridge motor driver IC designed to deliver robust and efficient control for DC motor applications. As part of Infineon’s broad portfolio of automotive and industrial power products, this driver combines high current capability with advanced protection features, making it a preferred solution in demanding environments such as automotive systems, industrial automation, and robotics.

At the core of the BTN7970BAUMA1 is a proprietary MOSFET technology that enables low on-state resistance and high switching efficiency. The device can handle a continuous output current of up to 70 A, with a peak current capability reaching 100 A, allowing it to drive high-power motors with minimal power dissipation. This high-current capacity is complemented by an operational voltage range from 5.5 V to 28 V, covering typical automotive and industrial supply voltages.

One of the key advantages of the BTN7970BAUMA1 is its high level of integration. The IC incorporates a PWM-controlled half-bridge, along with built-in protection circuits including over-current protection (OCP), over-temperature shutdown (OTSD), and under-voltage lockout (UVLO). These features enhance system reliability by safeguarding against fault conditions that could damage the motor or the driver itself.

The device also supports PWM frequency compatibility up to 25 kHz, enabling smooth and noiseless motor operation. Its diagnostic functionality provides feedback on system status, which is critical for applications requiring precise monitoring and control.

With its compact TO-263-7 package, the BTN7970BAUMA1 offers an excellent power-to-size ratio, simplifying PCB layout and thermal management. Its robust design and high performance make it ideal for applications such as electric power steering, throttle control, hydraulic pumps, and heavy-duty motor drives.

ICGOODFIND: The Infineon BTN7970BAUMA1 stands out for its high current handling, integrated protections, and automotive-grade robustness, providing engineers with a reliable and efficient solution for high-power motor control.
