RAJ306010

RAJ306001, RAJ306010 General-Purpose Motor Control IC Datasheet 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. 2.
