FT8132

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 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 pin or I²C interface. 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 various protection features, including 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 50μA.
