BA5995FM

BA5995FM Optical disc ICs BTL driver for CD/CD-ROM BA5995FM The BA5995FM is 4-channel BTL driver IC for driving actuator and motor of CD-ROM. Power package of HSOP-M28 pin enables to make set smaller. This IC is available for low voltage DSP. !Applications CD-ROM, others !Features 1) Wide dynamic range. (4V (typ.) at PreVCC=12V, PowVCC=5V, RL=8Ω) 2) Thermal shut down circuit built in. 3) Separating VCC into Pre and Power (Power divides into CH1, 2 and CH3/4), can make better power efficiency, by low supply voltage drive. 4) Stand by operated individually CH2 and CH1/3/4. 5) Built-in mute(CH1) circuit. 6) Suitable for low operation voltage DSP by wide D-range pre opamp. !Absolute maximum ratings (Ta=25°C) Parameter Symbol PreVcc, PowVcc Pd IoMax Topr Tstg Limits 13.5 2.2 1 ∗1 ∗2 Unit V W A ˚C ˚C Power supply voltage Power dissipation Max output current Operating temperature range Storage temperature range −35 to +85 −55 to +150 ∗1 On less than 3% (percentage occupied by copper foil), 70mm×70mm, t=1.6mm, glass epoxy mounting.
