Infineon BSP752RXUMA2: High-Current PROFET™ Smart Power Switch for Automotive Applications

The Infineon BSP752RXUMA2 represents a significant advancement in power management for the demanding environment of modern automotive systems. As a member of Infineon's renowned PROFET™ (Protected FET) family of smart high-side switches, this device is engineered to control, protect, and diagnose high-current loads with exceptional precision and reliability.

Designed specifically for 12V automotive applications, the BSP752RXUMA2 is capable of driving a wide array of resistive, inductive, and capacitive loads—from solenoids and valves to motors and heating elements—with a continuous output current of up to 30A. Its robust construction is centered around a vertical N-channel power MOSFET, which ensures very low typical on-state resistance (R_DS(on)), leading to minimized conduction losses and superior thermal performance. This high efficiency is critical for reducing heat generation and improving the overall energy footprint of the vehicle's electrical system.

Beyond simple switching, its "smart" capabilities are a cornerstone of its design. The device integrates a comprehensive suite of advanced protection and diagnostic features that safeguard both the switch itself and the connected load. These include protection against overload, short-circuit, over-temperature, and over-voltage conditions. A key feature is its sophisticated current sense diagnostic with a proportional (PSC) output, which provides a precise, analog voltage signal linearly related to the load current. This allows the host microcontroller to perform real-time monitoring for predictive maintenance, fault detection, and system status reporting, which is vital for functional safety and meeting standards like ISO 26262.

Housed in a PG-TO263-7-43 package, the device offers excellent power dissipation and is suitable for automated assembly processes. Its automotive-grade qualification ensures it meets the stringent AEC-Q100 standards, guaranteeing performance and longevity under the harsh conditions of the automotive environment, including wide temperature fluctuations and high electrical noise.
