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.

Applications Fan motors P-
