Infineon TLE72093RAUMA1 High-Current Half-Bridge Motor Driver IC: Powering Precision Motion Control

The Infineon TLE72093RAUMA1 represents a pinnacle of integration and robustness in the realm of motor control. Designed specifically for demanding automotive and industrial applications, this high-current half-bridge driver IC is engineered to deliver exceptional performance, reliability, and control for DC and brushless DC (BLDC) motors.

At its core, the device integrates two independent half-bridge channels, capable of being configured in parallel to drive loads with currents up to 30A continuously. This high-current capability makes it an ideal solution for driving actuators, pumps, fans, and various other motor types found in modern systems. The IC operates from a wide supply voltage range, typically from 5.5V to 28V, comfortably covering standard 12V and 24V automotive and industrial power systems.

A key strength of the TLE72093RAUMA1 is its high level of integration, which significantly reduces the need for external components. It features built-in protection functions that are critical for system longevity and safety. These include overtemperature shutdown, overcurrent protection (ISEN), undervoltage lockout (UVLO), and active short-circuit protection. This comprehensive suite ensures the driver and the connected motor are safeguarded under fault conditions, preventing catastrophic failures.

Control is facilitated through dedicated Input (IN) and Enable (EN) pins for each half-bridge, allowing for simple interfacing with a host microcontroller (MCU). The driver utilizes a MOSFET technology with very low RDS(on), which minimizes power dissipation and maximizes efficiency. This results in cooler operation and higher overall system reliability, even under high-load conditions.

Housed in a compact and thermally efficient PG-DSO-36-47 package, the device is optimized for space-constrained PCB designs while effectively managing the heat generated during operation. Its AEC-Q100 qualification ensures it meets the stringent reliability standards required for automotive electronics, making it a trusted choice for safety-critical applications.

ICGOODFIND: The Infineon TLE72093RAUMA1 stands out as a highly robust and integrated solution for high-current motor driving. Its combination of parallel operation capability, extensive built-in protection features, and automotive-grade reliability makes it an superior choice for designers seeking to create efficient, compact, and durable motion control systems.
