The MOTIX Bridge BTM90xx family of full-bridge/H-bridge integrated circuits (ICs), created especially for brushed DC motor applications, is the latest addition to Infineon Technologies’ product line.
The MOTIX low-voltage motor control IC portfolio, which includes highly integrated system-on-chip (SoC) solutions and driver ICs, is enhanced by the new BTM90xx full-bridge ICs.
Formerly pricey features are now standard due to the automotive industry’s ongoing evolution. Smart low-voltage motors will become increasingly crucial in determining how the vehicle’s user experience is shaped. Automobile makers are searching for more reliable, economical, and energy-efficient semiconductor solutions that can function well even in the most challenging circumstances.
BTM90xx devices are specifically designed for automotive applications, including zone control modules, doors, mirrors, seats, and bodies. To enable use in safety-related applications as well, accompanying safety documentation is available.
The BTM90xx Family is Characterized by a High Functionality to Enable:
- Intelligent and tiny motor control solutions.
- 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).
