The RT7075 is a two-in-one application specific IC which consists of a 3-phase motor controller and a gate driver designed for PMSM/BLDC motor applications. The RT7075 integrates the ARM 32-bit Cortex-M0 core with peripheral circuits to perform field oriented control (FOC) and sensorless motor control. In additions, system level peripheral functions, such as ADC, DAC, communication interface, SVPWM, watchdog timer, current sensing, undervoltage-lockout (UVLO), short circuit protection(SCP) and locked-rotor protection are integrated so as to reduce component count, PCB size and system cost. </p>Furthermore, the RT7075 drives external N-Channel MOSFETs in three half-bridge configuration with an external bootstrap network up to 600V. </p>A dead time control is built-in to prevents shoot-through of the external N-Channel MOSFETs. </p>The RT7075 is available in LQFP-48L 7x7 package.</p>
