FU5821 Series

The high-performance motor drive chip incorporates ME core and 8051 core. ME core integrates Smart Engine to complete calculations for high-speed motor control. 8051 core is used for parameter configuration and routine processing. Most of 8051 core instruction cycle takes 1 or 2 clock cycle(s). The dual cores work in parallel to achieve high-performance motor control. The chip integrates high-speed comparators, pre-driver, ADC, CRC, I²C, UART, Timers, PWM and high-voltage LDO, which are essential for square wave control of Hall-based single-phase BLDC motors.
