About

What are typical automotive BLDC motor applications?

Typical BLDC motor applications for automotive include powertrain, chassis, safety, and ADAS systems such as electric power steering, brake booster, MHEV starter generator, active roll control, HVAC compressor, transfer case, pumps and fans. In general, we see a strong growth of BLDC motor applications within the car as more and more premium functions become standard.

Additionally, as cars become more autonomous and connected, safety plays an increasingly crucial role. Here EPS and braking systems, for example, require solutions that are state-of-the-art, compact in design, and with a broad range of monitoring and diagnostic features. Our?MOTIX? gate driver ICs portfolio for BLDC motor control is positioned perfectly here to address the needs of the automotive industry.

ISO 26262 functional safety
MOTIX? gate driver ICs design-in support

MOTIX? gate driver ICs for BLDC motors are accompanied by an extensive portfolio of documentation such as application notes and design-in guidelines that support our customers in their design activities. In addition, we also offer a broad range of evaluation boards or shields for Arduino to make the evaluation of our products as easy as possible. Further collaterals that we provide include:

  • Diverse tools for configuration (e.g., ConfigurationWizards)
  • Device drivers for selected MOTIX? devices
  • Training videos?
  • Comprehensive support infrastructure?
  • Worldwide partner network for engineering services and software support
What is the adaptive MOSFET control feature??

Many MOTIX? motor control ICs use a patented concept of adaptive MOSFET gate drive. This multi-stage slew rate control enables EMC tuning via SPI, including adjusting slew rate with independence from dead-time and turn on/off delays. The on-board measurement and self-adaption of external MOSFET switching times allow balancing of power dissipation vs. EMC performance, adjust for MOSFET lot-to-lot variations and reduce the need for end-of-line calibration effort.

Adaptive MOSFET control is an integrated feature of the following MOTIX? gate driver ICs for BLDC motors: TLE9140, TLE9185 and TLE9189.?

New ISO 26262-compliant 3-phase gate driver ICs for EPS and braking

MOTIX? TLE9189x products are developed according to the ISO 26262 ASIL D development flow and are addressing the needs of safety relevant application such as?EPS?and?braking. The product family uses a conventional motor control concept via PWM input control and three integrated current sense amplifiers for current ground measurement with a precise configurable reference voltage (3.3/5V). This device will be Grade 0-qualified and offered in both a TQFP-48 and in a smaller VQFN-48 package, which allows for a flexible design.
