12V Small Motor Solution

Renesas' 12V Small Motor Solution offers a practical BLDC motor control system designed for pumps and fans. This solution utilizes three control methods, including Field Oriented Control (FOC) 3-/1-shunt and trapezoidal control. It makes use of the onboard RL78/F24 low-power automotive microcontroller's peripherals to enable a compact design that can be easily mounted into the motor housing.

System Benefits:

• Easy to Start
  • Complete reference design (circuit diagram, PCB design) including characteristic data
  • Provides three types of sample control software (FOC 3-/1-shunt, trapezoidal)
• Design Flexibility
  • Sample hardware and software to support motor control development
  • Reference design capable of driving motors up to 100W.
• Cost Efficiency
  • Small board size, designed to incorporate into the motor housing (60mm x 56mm)
  • Sensorless FOC control (1-shunt) uses a new timer function (asymmetric PWM output), and a built-in comparator circuit for overcurrent detection.
