Richtek has developed integrated control models for brushless DC motor drivers in three phase fan systems. Richtek’s two-in-one model consists of a 3 phase motor controller with an integrated gate driver, which specifically designed for PMSM/BLDC motor applications with robust protection features. The brushless DC motor controller IC also integrates a PWM current controller to drive a BLDC motor through motion commands from a built-in micro controller.
