The RAJ306000 is a motor control IC that can easily control three-phase brushless DC (BLDC) motors that are used in battery-operated applications including power tools, drones, communication robots, and cleaning robots. With its built-in high-function pre-drivers and RL78/G1F microcontroller (Flash ROM: 64KB) for motor control, the RAJ306000 drives a BLDC motor safely and at low power (high efficiency), facilitating BOM cost reduction and other requirements.  

 

Features

Compact: Up to 50% size reduction*

Integrates innovative high-performance analog circuitry.

 

Efficient: Up to 35% motor drive power dissipation improvement*

500mA pre-driver includes proprietary performance optimization circuit.

 

Standard: Common platform from 6V to 30V

Double boost function enables platform reuse across motor voltages.

 

Sensor-less: High performance sensor-less motor drive control

Reliable operation for low to high speed.

Complete Evaluation and Development Environment

We will continue to provide motor control evaluation boards and sample programs to help accelerate time to market. Existing RL78/G1F integrated development environments, compilers and libraries can be used for program development.

  • E1 Emulator for RL78 series
  • Renesas IDE
  • Also, IAR compatible
  • Evaluation board (PTP3-a):

             Includes MOSFET (6 pcs)

            Sample firmware

  • Evaluation and development require only connection to a motor

ARGOS Evaluation Boards

Motor Control Debugging Tool

  • Supports ICS (In-Circuit Scope) tool:
  • Display waveforms of internal program variables while the motor is rotating to graphically confirm behaviors.

    Improves debugging efficiency, and detection of anomalous behavior.
