TC78B025FTG
TOSHIBA CMOS Integrated Circuit Silicon Monolithic 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 О© (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 P-VQFN24-0404-0.50-002
