RAJ306001 and RAJ306010 are general-purpose motor control ICs for three phase Brushless DC motor applications. RAJ306001 and RAJ306010 combine MCU(RL78/G1F) and a pre-driver in a single package. The pre-driver includes half bridge gate drivers, 5V regulator, a current sense amplifier, hall IC comparators, Back-EMF amplifier, and various protection functions (overtemperature, over/under voltage, overcurrent and the motor lock detection).
Three half bridge gate drivers provide the high efficiency and high flexibility by adjustable gate drive peak current (500mA), self-align dead time generator, selectable gate drive voltage, and control signal configuration function. Self-align dead time generator prevents the short-through current and provides the safe evaluation environment.
MCU supports H/W of the safe standard of IEC60730. The development tools of the RL78 family are available. This IC can realize the suitable motor control and performance corresponding to each application by F/W construction and optimization of register settings.

評估板RAJ306010 RSSK
This product is a kit for evaluating motor system using RAJ306010. It consists of a board with RAJ306010mounted, a small 24V motor, and a connecting cable.
RAJ306010 is initially equipped with a sample code for 120 conduction control using a Hall IC, and a basicevaluation of motor control can be performed simply by connecting a 24V DC power supply and the attachedmotor. In addition, it is possible to connect and evaluate a motor and MOSFET prepared by user.
評估板RAJ306010 RSSK主要特性:
1. Easy to start the motor control evaluation with RAJ306010.
Since reference firmware has already been written on the RAJ306010, by connecting the attached smallmotor to the board and supplying power, evaluation can be start immediately.
2. High expandability and operability by small board (about B6 size: 148mm * 125mm).
The board is small and easy to operate, but, since switches, potentiometers, LEDs and thermistors aremounted, their functions can be used by using the user program.
3. Connectable to the external MOSFET board.
By setting the switching pin, it is possible to select mounted MOSFET and external MOSFET.
4. Various sample codes for the basic motor drive.
Sample code of basic control required for BLDC Motor control can be downloaded from the website
■ Hall IC 120 conduction control
■ Hall IC 120 energization speed control
■ Hall IC 120 conduction control
■ Hall IC 120 energization speed control
5. Support Desktop Lab ICS tool. (ICS: PC tool for waveform display)
ICS is a tool for monitoring and changing global variables in operation from a PC. Note.2
