3-channel BTL driver for CDs, CD-
ROMs, DVDs and DVD-ROMs
BA5932FP
The BA5932FP is a 3-channel BTL driver designed for CD and DVD player actuators and loading drives. The actuator
drive can be set to the desired gain and f characteristic with attached components, making this IC adaptable for a wide
array of applications.
FApplications
CD and DVD players, CD-ROM drives, DVD-ROM
drives, and other optical disc devices
FFeatures
1) 28-pin HSOP package for application miniaturiza-
tion.
3) Positive and negative input pins, for a wide range of
input types, including reverse phase input.
2) Gain is adjustable with an attached resistor.
FAbsolute maximum ratings (Ta = 25_C)

FOperation notes
(1) Mute input (pin 1) truth table
(3) Loading driver logic input (pins 13, 17) truth table
(2) Analog switch input (pin 10) truth table
(4) The BA5932FP has an internal thermal shutdown
circuit. Output current is muted when the chip tempera-
ture exceeds 175_C (typically) and restored when the
chip temperature falls to 150_C (typically).
(5) Connect the IC to a 0.1µF bypass capacitor to the
power supply, at the base of the IC.
(6) Be sure to connect the radiating fin to an external
ground.
