What BLDC motor gate drivers are available for consumer applications? 

The MOTIX™ portfolio comprises ideal solutions for consumer and professional power tools, as well as service robots such as electric vacuum cleaners and lawn mowers. Light electric vehicles such as e-bikes, e-scooters, and low-speed electric cars that use MOTIX™ gate driver ICs with 24 V, 36 V, or 48 V battery capabilities exhibit increased battery life, longer operating range, and reduced charging times.

With MOTIX™ 6EDL7151 and MOTIX™ 6EDL7141 stand-alone 3-phase gate driver ICs are available offering over 50 programmable parameters and using a built-in digital SPI interface. Both products are fully configurable to drive a wide range of MOSFETs to yield the best possible system performance.

MOTIX™ IMD700A/IMD701A motor control SiP (system-in-package) solutions are fully programmable motor controllers integrating the XMC1404 microcontroller with the 6EDL7141 3-phase gate driver IC in one package.

What is adaptive MOSFET control?

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.
