January 16, 2025 /SemiMedia/ — Infineon Technologies AG has recently launched the MOTIX™ Bridge BTM90xx series, a portfolio of full-bridge/H-bridge integrated circuits (ICs) designed specifically for brushed DC motor applications. As the automotive industry continues to evolve, features once considered premium are now becoming standard. Smart low-voltage motors will play an increasingly important role in shaping the future in-vehicle user experience. Automotive manufacturers are seeking more reliable, energy-efficient, and cost-effective semiconductor solutions that perform effectively even under harsh conditions.

The newly introduced BTM90xx full-bridge ICs further enhance the MOTIX low-voltage motor control IC portfolio, covering a range of solutions from driver ICs to highly integrated system-on-chip (SoC) solutions. While not limited to automotive applications, the BTM90xx devices are particularly optimized for use in door, mirror, seat, body, and zone control modules. Additionally, accompanying safety documentation supports their use in safety-critical applications.

The BTM90xx family is characterized by a high functionality to enable intelligent and tiny motor control solutions. The devices, with a supply voltage range for normal operation of 7 V to 18 V (extended 4.5 V to 40 V) offer extensive protection and diagnostic functions such as overtemperature, undervoltage, overcurrent, cross-current or short-circuit detection. Currents are measured for both the high-side and low-side switches and the devices are suitable for automotive applications with a current limit of at least 10 A (BTM901x) or 20 A (BTM902x). PWM operation is possible for frequencies up to 20 kHz. The BTM9011EP and BTM9021EP are SPI variants and support pin-saving daisy chain function to help reduce overall system costs. BTM9021 in addition features an integrated watchdog. The BTM90xx's tiny TSDSO-14 (4.9 x 6.0 mm) package reduces the overall PCB board space required and features a large exposed pad that simultaneously improves the device's thermal performance.

To simplify the evaluation and design-in process for MOTIX BTM90xx, Infineon also provides a comprehensive support package, including technical product documentation, simulation models, a tool for calculating power dissipation, evaluation boards and Arduino example code. In addition, software (MOTIX BTM90xx Device Driver) and the MOTIX Full Bridge IC Configuration Wizard are available for free at the  Infineon Developer Center (IDC).

The MOTIX devices BTM9010EP, BTM9011EP, BTM9020EP and BTM9021EP can be ordered now. For more information, please visit www.infineon.com/BTM90xx.
