RAJ306010GNP#HA1

Overview

The RAJ306010GNP#HA1 is a general-purpose motor control integrated circuit designed for three-phase brushless DC motor applications. It integrates an RL78/G1F microcontroller and a pre-driver within a single package. The device operates with a supply voltage range of 6V to 42V and supports an operating temperature range of -40°C to +85°C. Key electrical parameters include a maximum output current of 500mA, a typical standby current of 64µA, and a working power supply current of 13.5mA. It utilizes a VFQFPN-64 surface-mount package.

Feature Summary

• Integrates a 16-bit CISC CPU (RL78/G1F) with 64KB flash ROM and 5.52KB RAM alongside a pre-driver in a single package.
• Features three half-bridge gate drivers with adjustable peak currents up to 500mA and self-aligning dead-time generation.
• Includes built-in protection mechanisms such as UVLO, overtemperature, overcurrent, overvoltage, and motor lock detection.

Applications

• Three-phase brushless DC motor control systems
• General-purpose motor driver designs requiring integrated MCU functionality
• Applications supporting Hall sensor or sensorless motor operation

Procurement Notes

Verify the specific suffix #HA1 against official Renesas documentation to confirm packaging details, as ordering suffixes may indicate variations in reel specifications or labeling. Confirm current availability status directly with authorized distributors, as this component may be subject to limited supply or last-time-buy conditions. Ensure compliance with RoHS directives and moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this component when a combined MCU and pre-driver solution is required for three-phase BLDC motors. It is suitable for designs needing adjustable gate drive currents and integrated protection features. Consider the 64-pin VFQFPN package constraints and the 6V to 42V input voltage range. Verify that the integrated RL78/G1F resources meet the application's processing requirements.
