TC78B004FTG,EL, Motor / Motion / Ignition Controllers & Drivers Sensored Brushless Motor Controller with Intelligent Phase Control (InPac),

Semiconductors\Power Management ICs\Motor/Motion/Ignition Controllers & DriversTC78B0 Brushless Motor Driver ICs Toshiba TC78B0 Brushless Motor Driver ICs are designed to control motor rotational speed by changing the PWM duty cycle. These driver ICs feature a three-phase full-wave drive, sine-wave PWM drive, brake function terminal, selectable rotation direction, overcurrent detection circuit, and thermal shutdown circuit. The brushless motor driver ICs have a 150° trapezoid PWM chopper system that controls the motor rotational speed. The one-hall drive system and current sense resistor-elimination system reduces the number of external components and saves space on the boards. These TC78B0 brushless motor drive ICs are ideal for fan motors.
