FU6832S is a high-performance motor drive dedicated chip with integrated motor control engine (ME) and 8051 core. ME integrates many hardware modules such as FOC, MDU, LPF, PI, SVPWM/SPWM, etc., and can automatically complete motor FOC/BLDC operation control by hardware. ;_8051 core is used for parameter configuration and daily transaction processing, and dual cores work in parallel to realize various high-performance motor control. Most of the 8051 core instruction cycles are 1T or 2T, and the chip integrates high-speed operational amplifiers, comparators, Pre-drivers, high-speed ADCs, high-speed multipliers/dividers, CRC, SPI, I2C, UART, LIN, various TIMER, PWM and other functions, built-in high-voltage LDO, suitable for square wave, SVPWM/SPWM, FOC drive control of BLDC/PMSM motors.

FU6832S package form: FU6832S (SSOP24).

characteristic

■Supply voltage:

FU6832S:

Single power supply high voltage mode: VCC_MODE=0, the external power supply is input from VCC to 5~28V, and VDD5 is generated by the internal LDO
