FT8215Q1

FT8215Q1 is a three-phase brushless DC (BLDC) motor driver IC with integrated MOSFETs, featuring sensorless field‑oriented control (FOC). Due to a high level of integration, the chip has few peripheral components and features low noise and small torque ripple. Motor parameters, startup control parameters, and speed control modes can be configured via GUI, and are stored in built-in EEPROM. Analog voltage input, PWM, I²C interface, or CLOCK mode is available for motor speed control. Moreover, the chip integrates the speed indicator to read motor speed in real time via FG/RD/SDA or SPEED/SCL pin. Constant speed control mode, constant current control mode, or constant 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), temperature sensor detect (TSD), motor stall protection, phase loss protection, etc. Sleep-mode current of the chip is about 40μA.
