RAJ306001GNP#HA1

Overview

The RAJ306001GNP#HA1 is a general-purpose motor control IC designed for three-phase brushless DC motor applications. It integrates an RL78/G1F microcontroller and a pre-driver in a single package. The device operates within a supply voltage range of 6V to 30V and supports an operating temperature range of -40°C to +85°C. Key electrical parameters include a typical operating power supply current of 13.5mA at VM=22.5V, a standby current of 64µA, and a maximum output current capability of 30mA. The unit is housed in a 64-pin QFN surface-mount package with dimensions of 8mm x 8mm and a height of 0.8mm.

Feature Summary

• Integrates a 16-bit CISC CPU (RL78/G1F) with 64KB Flash ROM and 5.52KB RAM alongside a pre-driver block.
• Includes three half-bridge gate drivers for six N-MOSFETs with adjustable peak current up to 500mA.
• Supports both Hall sensor-based and sensorless motor control configurations.
• Features integrated protection mechanisms including UVLO, overtemperature, overcurrent, overvoltage, and motor lock detection.

Applications

• Three-phase brushless DC motor control systems
• General-purpose industrial motor drives
• Home appliance motor management

Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm the specific suffix #HA1 corresponds to tape-and-reel packaging requirements for automated assembly processes. Ensure compliance with RoHS directives and moisture sensitivity level classifications prior to storage and soldering operations.

Selection Notes

Select this component when a combined MCU and driver solution is required for BLDC applications. Consider the 30mA output limit for lower-power loads compared to higher-current variants. Evaluate the 64-pin QFN footprint against available PCB space constraints and thermal dissipation needs for the target enclosure design.

Part Context

This part belongs to the RAJ306001 series of mixed-signal motor controllers. It shares architectural similarities with the RAJ306010 but differs in output current ratings and specific feature sets. The series targets cost-sensitive applications requiring integrated control logic and power driving capabilities in a compact form factor.

Replacement Considerations

Official documentation states that the RAJ306001 series is not recommended for new designs and has no alternative product available. No public confirmed substitute part numbers are listed by the manufacturer.
