The RT7075 is the two-in-one IC which consists of 3 phase motor controller and gate driver delicatedy designed for PMSM/BLDC motor applications.
The RT7075 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, undervoltage-lockout (UVLO), over current protection (OCP) and motor lock protection, so as to reduce component count, board space and system cost. Furthermore, the RT7075 drives the external devices N-MOSFETs or IGBTs in a half-bridge configuration with an external bootstrap network up to 600V. A dead time control prevents shoot-through of the external devices. The RT7075 is available in a LQFP-48L 7x7 package.
