Overview
Description
The RAA306012 is a smart gate driver for 3-phase brushless DC (BLDC) motor applications. It integrates three half-bridge gate drivers that are capable of driving up to three N-channel MOSFET bridges and supports bridge voltages from 6V to 65V. Each gate driver supports up to 0.64A source and 1.28A sink peak drive current with adjustable drive strength control. Adaptive and adjustable dead times are implemented to ensure robustness and flexibility. The active gate holding mechanism prevents Miller effect induced cross-conduction and further enhances robustness.
The device integrates power supplies that power internal analog and logic circuitry, high-side/low-side gate drivers, and a dedicated supply for powering external microcontrollers. The RAA306012 also features a low-power sleep mode that consumes only 28μA to maximize battery life in portable applications.
