RAJ306001 and RAJ306010 Motor Driver ICs for Simplifying BLDC Motor Control Design in Battery-Powered Applications

Renesas Electronics Corporation has introduced RAJ306001 and RAJ306010 motor drive ICs that deliver improved low-speed or high-speed rotation and high torque control at a smaller board space and reduced solution cost. The newsystem-in-package (SiP) solutionswere designed to simplify brushless DC (BLDC) motor control design for a wide range of battery-powered applications such as power tools, drones, water pumps, vacuums, cleaning robots, fans, and other systems.

With an integratedRL78/G1F microcontroller (MCU) and pre-driverin an8x8mm QFN package, both the single package motor control ICs can control three-phase BLDC motors used in a wide range of battery-powered devices. The fully integrated SiP factor allows the users to reduce up to 30 external components eventually reducing the area of the device up to 50% with low control system costs.

Designed with a self-aligned dead time(SADT) the new ICs prevent the shoot through and offer adjustable pre-driveroutput current capacity up to 500mA. This helps driving large-capacity MOSFETs making heat dissipation design easier and allows the MOSFETs to drive at the switching timing – reducing FET switching margin times to approximately 1/10 the time compared with conventional systems.

Features of RAJ306001 and RAJ306010 Motor Control ICs

• Renesas MCU and pre-driver integrated into a single 8x8 mm QFN package, including a charge pump, linear regulators, current detection, programmable slew rate control, and BEMF detect circuitry for sensor-less operation
• 高集成优化板空间并降低控制系统BOM成本
• Supports operating ranges from 6-30V (RAJ306001) and 6-42V (RAJ306010)
• SADT generator allows MOSFETs to run cooler while maintaining high efficiency
• Sensor-less motor control enables stable operation from low-speed to high-speed rotation and could eliminate the Hall ICs
• Integrated safety functions, including IEC 60730 safety standard support, can detect errors and halt the motor if an error occurred
