RT7075
RT7075 is 3 Phase PMSM/BLDC Motor Controller manufactured by Richtek.
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, munication interface, SVPWM, watchdog timer, current sensing, over current protection and over temperature protection, so as to reduce ponent 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. A dead time control prevents shoot-through of the external devices. The RT7075 series is available in a LQFP-48L 7x7 package.
