The RAJ306000 is a motor control IC that can easily control three-phase brushless DC (BLDC) motors that are used in battery-operated power tools, drones, communication robots, cleaning robots, and so on. With its built-in high-function pre-drivers and RL78/G1F microcontroller (flash ROM: 64 KB) for motor control, the RAJ306000 drives a BLDC motor safely and at low power (high efficiency), facilitating BOM cost reduction and other requirements. It has the following 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)
- Evaluation and development require only connection to a motor
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 de-bugging efficiency, and detection of anomalous behavior.
