® RT7075 3 Phase PMSM/BLDC Motor Controller with Gate Driver General Description The RT7075 series is the two-in-one IC which consists of 3 phase motor controller and gate driver delicatedy designed for PMSM/BLDC motor applications. RT7075 series integrates the ARM 32-bit Cortex-M0 core and peripheral circuits to perform a FOC and sensorless motor control. The IC has integrated various system level peripheral functions, such as ADC, DAC, communication interface, SVPWM, watchdog timer, current sensing, over current protection and over temperature protection, so as to reduce component count, board space and system cost. Furthermore, RT7075 series drives the external devices N-MOSFETs or IGBTs in a half-bridge configuration with an external bootstrap network up to 600V.
