1. Overview

RAJ306001 and RAJ306010 are general-purpose

motor control ICs for three phase Brushless DC

motor applications. RAJ306001 and RAJ306010

combine MCU(RL78/G1F) and a pre-driver in a

single package. The pre-driver includes half bridge

gate drivers, 5V regulator, a current sense amplifier,

hall IC comparators, Back-EMF amplifier, and

various protection functions (overtemperature,

over/under voltage, overcurrent and the motor lock

detection).

Three half bridge gate drivers provide the high

efficiency and high flexibility by adjustable gate drive

peak current (500mA), self-align dead time

generator, selectable gate drive voltage, and control

signal configuration function. Self-align dead time

generator prevents the short-through current and

provides the safe evaluation environment.

MCU supports H/W of the safe standard of

IEC60730. The development tools of the RL78 family

are available. This IC can realize the suitable motor

control and performance corresponding to each

application by F/W construction and optimization of

register settings.
