TOSHIBA CMOS Integrated Circuit Silicon Monolithic

TC78B015FTG

3-phase Driver for Brushless DC Motors

The TC78B015FTG is for three-phase full-wave brushless DC

motor with 150-degree trapezoid PWM chopper system. They

control motor rotational speed by changing the PWM duty, based

on the speed control input. Hall signal is supported to one sensor

for the TC78B015FTG.
