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.
