| 01W109A 4-channel BTL driver BA5824FP Description BA5824FP incorporates 4-channel drivers that operate the motor and the actuator for car CD players. CH1,2 and CH3,4 each have power supply independently. The highly efficient drive can be achieved due to the low voltage operation. The input of CH4 can be switched by the control pin.
