Technical content

TI’s Smart Gate Drive technology can reduce system cost by integrating up to 24 external components typically used in standard gate drivers, reducing PCB size and minimizing controller GPIOs.

TI’s Smart Gate Drive technology enables reliable protection with MOSFET drain-source and gate-source fault detection, automatic dead-time control and preventing false FET turn-on due to coupling.

TI’s Smart Gate Drive technology simplifies design through integrated automatic dead-time and by providing programmable gate drive current to optimize EMI without sacrificing switching losses.

Reduce power losses with improved current regulation. TI smart tuning features automatically adapt current chopping decay modes to reduce power losses and thermal dissipation compared to a poorly-tune

Minimize noise and vibration by preventing loss of current regulation while also ensuring minimal step losses through automatically tuned decay modes.

Decay mode selection made easy. TI smart tuning features automatically set decay mode ratio – eliminating the need for fine-tuning during motor design.
