BA5932FP

Optical disc ICs 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) 219 Optical disc ICs FBlock diagram BA5932FP 220 Optical disc ICs FPin descriptions BA5932FP 221 Optical disc ICs FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC = 12V, LDVCC = 5V, RL = 8Ω) BA5932FP 222 Optical disc ICs FMeasurement circuit BA5932FP 223 Optical disc ICs FApplication circuit BA5932FP 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 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...
