ICs for Motor Control

All-in-one ICs for motor control that combine analog front-end and sophisticated pre-drivers with RL78 MCUs optimal for BLDC motor control of power tools and other equipment

 

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.

Funcionalidades

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

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.

 

Below you will find information to support the development of your application.
