FT8133

FT8133Q is an IC with built-in pre-driver for three-phase BLDC motor driver applications. Due to a high level of integration, the chip has few peripheral components and is featured with low noise and small torque ripple. Motor parameters, startup control parameters and speed regulation mode can be configured via GUI, and are stored in built-in EEPROM. Analog voltage, PWM, I2C interface or CLOCK mode is available for motor speed regulation. Moreover, the chip integrates speed indicator to read motor speed in real time via FG pin or I2C interface. Speed-loop control mode, current-loop control mode or voltage-loop control mode is optional. In addition, the chip is secured with a wide range of protection features, including over-current protection (OCP), under-voltage lockout (UVLO), over-voltage lockout (OVLO), motor lock protection (MLP), phase loss protection, abnormal Hall input detection (HALLERR) protection, etc. Sleep-mode current of the chip is about 60μA.
