3-channel BTL driver for CDs, CDROMs, 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 miniaturization. 2) Gain is adjustable with an attached resistor. FAbsolute maximum ratings (Ta = 25_C)
3) Positive and negative input pins, for a wide range of input types, including reverse phase input.
FRecommended operating conditions (Ta = 25_C)

Analog switch input (pin 10) truth table (4) The BA5932FP has an internal thermal shutdown circuit. Output current is muted when the chip temperature 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...
