BTM7751G: Infineon's High-Current Half-Bridge Motor Driver IC

In the rapidly advancing fields of automotive, industrial automation, and robotics, the demand for robust, efficient, and intelligent motor control solutions is higher than ever. Addressing this need, Infineon Technologies introduces the BTM7751G, a highly integrated high-current half-bridge driver IC engineered for superior performance and reliability. This device stands out as a pivotal component for designers seeking to power and precisely control DC motors, solenoids, and other inductive loads.

The BTM7751G is a member of Infineon’s well-established NovalithIC™ family, which brilliantly combines a high-side and a low-side switch in a single, compact package. This innovative integration is built upon advanced MOSFET technology, enabling the IC to handle impressive continuous currents up to 40 A and withstand peak currents even higher. This high-current capability makes it an ideal choice for demanding applications such as electric power steering (EPS) systems, hydraulic pumps, and advanced braking systems.

A key strength of the BTM7751G lies in its comprehensive suite of integrated protection features. These are crucial for ensuring system longevity and safe operation under fault conditions. The IC includes protection against over-current (OCP), over-temperature (OTSD), under-voltage lockout (UVLO), and over-voltage lockout (OVLO). Furthermore, it features a sophisticated diagnostic and protection circuit that provides fault feedback to the microcontroller, allowing for immediate and intelligent system responses to any anomalies.

The interface is designed for simplicity and noise immunity, accepting standard 3.3 V and 5 V TTL/CMOS logic levels for direct connection to a host microcontroller. This simplifies design-in and reduces the need for additional level-shifting components. The driver also boasts a very low standby current, which is a critical advantage in automotive applications where low quiescent current is mandatory for meeting strict energy consumption standards.

Housed in a robust PG-DSO-36-92 package, the BTM7751G offers excellent thermal performance and mechanical durability. The package is designed for efficient heat dissipation, which is paramount when driving high currents, ensuring the IC operates within its safe temperature range even under strenuous conditions.

ICGOODFIND Summary: The Infineon BTM7751G is a high-power, highly integrated half-bridge motor driver that excels in performance, reliability, and intelligence. Its exceptional current handling, extensive built-in protection, and simple control interface make it a top-tier solution for developing next-generation motor control systems in the automotive and industrial sectors.
