TC78B004FTG TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TC78B004FTG 3-phase Full-wave Sine-wave PWM driving Brushless Motor Controller with Speed Control Function 1. Outline TC78B004FTG is a 3-phase -wavfulle Sine-wave PWM driving brushless motor control IC with the speed control function. Sine-wave PWM driving with ph2-ase modulation enables driving in high efficiency and low noise condition. The speed control function which can change speed of the motor is built in this product. P-WQFN40-0606-0.50-001 Weight: 0.0849 g (typ.) 2. Features Sine-wave PWM driving system 2-phase modulation system with low switching loss Dead time function included External clock input FLL + PLL speed control circuit READY circuit output FG amplifier included Auto lead-angle control function included CW/Stop (Standby) / CCW / Brake functions included Current limitation function included Lock protection function included Note: This product has a MOS structure and is sensitive to electrostatic discharge. When handling this product, ensure that the environment is protected against electrostatic discharge by using an earth strap, a conductive mat and an ionizer. Ensure also that the ambient temperature and relative humidity are maintained at reasonable levels. The IC should be installed correctly. Otherwise, the IC or peripheral parts and devices may be degraded or permanently damaged. 2017 1 2017-10-25 Toshiba Electronic Devices & Storage Corporation TC78B004FTG 3.
