TOSHIBA CMOS Integrated Circuit Silicon Monolithic TC78B025FTG TC78B025FTG 1-hall sine-wave PWM driver for 3-phase brushless DC motors 1. Outline The TC78B025FTG is a 1-hall sine-wave PWM driver for 3-phase brushless DC motors. DMOS is used in output stages, realizing low-on-resistance of 0.2 Ω (total of high and low sides). A non-volatile memory (NVM) and a closed loop speed control function are incorporated. Cost can be suppressed without using microcomputers. 2. Applications Fan motors P-VQFN24-0404-0.50-002 Weight: 0.04g (typ.) 3. Features ● 1-hall sine-wave PWM drive ● Built-in closed loop speed control, configurable speed curve ● Low on resistance: RDS(H+L)=0.2 Ω (typ.) ● Driving current: 3.5 A max (peak) ● Operating voltage range: 4.
