RT7082A2M Description
The RT7082A2M 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 an LDO for gate driver supply. The RT7082A2M embeds the ARM 32-bit Cortex-M0 core with peripheral circuits to perform sensorless Field Oriented Control (FOC).
