FT8132 is an IC with built in pre driver designed for three phase BLDC motor drive applications .
Due to a high level of integration, the chip has few peripheral components and feature s with low oise 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 pin or I2C interface. Constant peed control mode, constant current control mode, constant power control mode or voltage loop control mode is optional. In addition, the chip is secured with various protection features, ncluding 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 current of the chip is about 60 μ A.
