FT8215 is an IC with built-in three-phase MOSFET designed for BLDC motor drive system.
Due to a high level of integration, few peripheral components are required. The chip 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, PWM, I2C interface or CLOCK mode is optional for motor speed regulation. Moreover, the chip integrates speed indicator, which reads motor speed in real time via FG pin or I2C interface. Speed 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), temperature sensor detect (TSD), motor lock protection (MLP) and phase loss protection. Sleep current of the chip is about 40μA.
