Renesas RAJ306001, RAJ306010

The RAJ306001 and RAJ306010 are general-purpose motor control ICs for three-phase Brushless DC motor applications. The RAJ306001 and RAJ306010 combine MCU(RL78/G1F) and a pre-driver in a single package. The pre-driver includes half-bridge gate drivers, a 5 V regulator, a current sense amplifier, hall IC comparators, a Back-EMF amplifier, and various protection functions (overtemperature, over/undervoltage, overcurrent protection, and the motor lock detection).

RTK0EML2C0S01020BJ - BLDC Motor Control Evaluation System for RAJ3060xx Motor Control ICs

• This is a kit for evaluating the BLDC motor system using the RAJ306010 motor control IC. It consists of a board with RAJ306010 mounted, a small 24V motor, and a connecting cable. The RAJ306010 is initially equipped with a sample code for 120° conduction control using a Hall IC, and a basic evaluation of motor control can be performed simply by connecting a 24 V DC power supply and the attached motor. In addition, it is possible to connect and evaluate a motor and MOSFET prepared by the user.
• BLDC motors have different control requirements than standard brush motors. Reference our BLDC Motor Control Algorithms page for additional information and guidelines.

Evaluation System Features:

• Easy to start the motor control evaluation with RAJ306010
• Reference firmware has already been written on the RAJ306010: by connecting the attached small motor to the board and supplying power, evaluation can be started immediately
• High expandability and operability by a small board (about B6 size: 148 × 125 mm)
• The board is small and easy to operate, but, since switches, potentiometers, LEDs, and thermistors are mounted, their functions can be used by using the user program
• Connectable to the external MOSFET board
• By setting the switching pin, it is possible to select mounted MOSFET and external MOSFET.
• Various sample codes for the basic motor drive
• Sample code of basic control required for BLDC Motor control can be downloaded from the website
• 120° conducting control with hall IC
• 120° conducting speed control with hall IC
• 120° conducting control by Sensor-less drive
• 120°s conducting control with hall IC
• Desk Top Lab ICS tool support (ICS: PC tool for waveform display)
• ICS is a tool for monitoring and changing global variables in operation from a PC
