FT8215

FT8215 is a highly integrated IC with built-in MOSFET for three-phase BLDC motor drive applications. Due to a high level of integration, the chip has few peripheral components and features 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 input, 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/RD/SDA or SPEED/SCL pin. Constant speed control mode, constant current control mode, constant power 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), temperature sensor detect (TSD), motor lock protection (MLP), under-voltage lockout (UVLO), phase loss protection, etc. Sleep-mode current of the chip is about 40μA.
