The RAA227063 is a smart gate driver IC for 3-phase sensorless 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, with 1A drive and 2A sinking current capability. It is equipped with an LDO that is fed directly from the input voltage, providing power to the MCU. Three accurate differential amplifiers with adjustable gain are integrated to support ground-side shunt current sensing with the S/H system, which provides results via one output channel to the MCU ADC input.
