FU6815 Series

The high-performance motor drive chip incorporates ME core and 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/PMSM motors. 8051 core is used for parameter configuration and routine processing. Most of 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, PWM (FU6815L/FU6815T), pre-driver (FU6865Q/FU6864Q/FU6864L), high-speed ADC, CRC, SPI, I²C, UART, Timers and built-in high-voltage LDO, which are suitable for FOC or square-wave based BLDC/PMSM motors.
