Toshiba TC78B0 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 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 1-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.
