Description
The RAJ306101 is a general-purpose motor control IC for 3-phase brushless DC (BLDC) motor applications. RAJ306101 combines a smart gate driver (RAA306012) and an MCU (RX13T) in a single package. The smart gate driver includes three half-bridge gate drivers, a buck switching regulator and a charge pump for the gate drive voltage, two LDOs for the internal analog and logic circuitry and MCU (3.3V to 5V adjustable), three accurate differential amplifiers, a BEMF sense amplifier, three general purpose comparators, and extensive protection functions.
The three half-bridge gate drivers are capable of driving up to three N-channel MOSFET bridges and support 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.
Three accurate differential amplifiers with adjustable gain support ground-side shunt current sensing for each bridge. The device can support both BLDC sensor/sensorless motor drive by the three general-purpose comparators or a BEMF sense amplifier.
