AOZ6866QI
Motor Control MCU's
Status: New
The AOZ6866Q1 high-performance motor drive chip incorporates an ME core and an 8051 core. ME core integrates FOC, MDU, LPF, PID, and SVPWM modules that allow for automatic calculation of FOC or square-wave control by the hardware for sensored/sensorless BLDC motors. 8051 core is used for parameter configuration and routine processing. Most of the 8051- core instruction cycle takes 1T or 2T clock cycle(s). The dual cores work in parallel to achieve high-performance motor control. The chip integrates high-speed operational amplifiers, comparators, pre-driver, high-speed ADC, CRC, SPI, I2C, UART, LIN, CAN, Timers, built-in high-voltage LDO, which are suitable for FOC or square-wave based BLDC motors.
