Part Number Device Category Portion Usage Description
IC TB6605FTG Motor control: 1pc TB6605FTG is a 3-phase full-wave sine-wave PWM brushless motor control IC.Sine-wave PWM driving with 2-phase modulation enables driving in high efficiency and low noise condition.
IC TC75S51F Op-Amp: 2pcs The TC75S51F/TC75S51FU/TC75S51FE is a CMOS singleoperation amplifier which incorporates a phase compensation circuit. It is designed with a low-voltage and low-current power supply; this differentiates this device from general-purpose bipolar op-amps.
IC TK20P04M1 MOSFET: 6pcs High-speed switching / Low gate charge / Low drain-source on-resistance / Low leakage current
