Smart 3-Phase Gate Driver

The RAA227063 is a smart gate driver IC for 3-phase Brushless DC (BLDC) motor applications. It integrates three half-bridge smart gate drivers that are capable of driving up to three N-channel MOSFET bridges and supports bridge voltages from 4.5V to 60V. Each gate driver supports up to 1A source and 2A sink peak drive current with programmable drive strength control.

Adjustable and adaptive dead-times are implemented to ensure robustness and flexibility. The active gate holding mechanism prevents a Miller effect-induced cross-conduction and further enhances robustness.
