Overview
Optical disc ICs 4-channel BTL driver for CD players BA5934FP The BA5934FP is a 4-channel BTL driver developed to drive CD player motors and actuators.
Perfect for compact applications with the use of the HSOP 28-pin power package.
FApplications CD players, CD-ROM FFeatures 1) In addition to internal drivers for the focus coil, tracking coil, and sled motor, it also contains a driver for the loading motor.
2) Perfect for compact applications with the use of the HSOP 28-pin power package.
3) Requires few external components.
FAbsolute maximum ratings (Ta = 25_C) 4) Driver gain is adjustable with a single externally connected resistor.
5) Internal thermal shutdown circuit.
6) External mute pin enables the muting of the output current for channel 4.

5V) BA5934FP 721 Optical disc ICs FMeasurement circuit BA5934FP 722 Optical disc ICs FCircuit operation (1) Driver block The input is the focus and tracking error signals from the servo pre-amplifier and the control signals for the motor system.
The input signal is normally centered at 2.
5V, and at the pre-amplifier, it undergoes V / I conversion to generate the current corresponding to the input voltage.
This is then passed through a resistor and sent to the internal reference voltage block.
BA5934FP This results in the output from the pre-amplifier being the signal at the center of the internal reference voltage.
Furthermore, at the V / I conversion, forward and reverse phases are generated and the BTL output is then gained through the driver buffer.
