FT8213 is an IC with built in MOS and pre driver designed for three phase BLDC motor driver applications.
It supports sensorless FOC and designs with a 1 Ω internal Rdson. 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 are stored in EFUSE. PWM, analog voltage input or I 2 C interface is available for motor speed regulation. Moreover, the hip integrates speed indicator to read motor speed in real time via FG pin or I 2 C interface. Constant speed control mode, constant air flow control mode, constant current control mode or pen loop control mode is optional. In addition, the chip is secured with a wide range of protection features, including phase loss protection, over voltage lockout (OVLO), over current protection (OCP), under voltage lockout (UVLO), current limiting protection (CLP), temperature sensor detect (TSD), motor lock protection (MLP), etc. Sleep mode current of the chip is about 45 μ A.
