TOSHIBA TC78B011FTG CDMOS Linear IC
Toshiba TC78B011FTG CDMOS linear IC is a three-phase PWM chopper pre driver for sensorless brushless motors. This linear IC is used in conjunction with 6 external MOSFET inverters to operate sensorless brushless motors with a wide output range. The motor speed of CDMOS TC78B011FTG can be controlled by analog voltage, PWM duty cycle, and I2C The TC78B011FTG IC can achieve closed-loop speed control function without the need for an external microcontroller. The IC also has built-in closed-loop speed control, and the speed curve is adjustable. TC78B011FTG IC can drive motors in Delta or Wye configurations. The operating voltage range of this linear IC is 5.5V to 27V, with an absolute maximum rated value of 30V. TC78B011FTG IC is suitable for fans, pumps, and portable vacuum motors.
