RT7084C2M Three-Phase PMSM/BLDC Motor Controller with Pre-Driver 1 General Description The RT7084C2M is an application-specific IC designed for PMSM/BLDC motor applications. This two-in-one ASIC integrates several functional circuits, including a 3-phase motor controller, a 3-phase gate driver, three bootstrap diodes, a 5V LDO, and a buck converter. The RT7084C2M embeds the ARM 32-bit Cortex-M0 core with peripheral circuits to perform sensorless Field Oriented Control (FOC). In addition, this ASIC provides several system-level peripheral functions, including filters at the ADC input, a communication interface, a thermal sensor, short circuit protection (SCP) and locked-rotor protection, to reduce component count, PCB size and system cost.
