BA5815FM

00W098A 5-channel driver for CD/DVD players BA5815FM Description The BA5815FM is a power driver IC for 5-channel CD and DVD players. Two channels incorporate filters and can connect PWM input directly. The additional 2 channels incorporate a standard operational amplifier. It can reduce the external components greatly. In the loading driver, output voltage can be adjusted to each device. Features 1) 4-channel BTL driver and 1-channel reversible driver 2) 2 channels are PWM input direct-coupled type. (Built-in primary filter) 3) 2 channels have standard operational amplifiers. 4) The device can be miniaturized due to the adoption of HSOP-M28 power package. 5) Built-in thermal shut down circuit 6) Wide dynamic range(9.2V(Typ.) at Vcc=12V, RL=8Ω) HSOP-M28 Dimension (Units : mm) 18.5±0.2 28 15 9.9±0.3 7.5±0.2 5.15±0. 1 2.2±0. 1 0. 1 1 0.8 0.35±0. 1 0.3Min. 0. 15 Applications DVD, CD players Absolute Maximum Ratings(Ta=25˚C) Parameter Power supply voltage Power dissipation Operating temperature range Storage temperature range Symbol Vcc Pd Topr Tstg –40 –55 Limits 13.5 2.2 ~ ~ ∗ Unit V W +85 +150 ˚C ˚C ∗Derating : 17.6 mW/˚C for operation above Ta=25˚C (70×70×1.6mm) glass epoxy board Recommended Operating Conditions(Ta=25˚C) Parameter Power supply voltage Symbol Vcc Min. 4.3 Typ. 12.0 Max. 13.2 Unit V November, 2000 0.25±0. 1 1 14 Electrical characteristics (Unless otherwise noted; Ta=25˚C, Vcc1,2=12V, BIAS=1.65V, RL=8Ω) Parameter Output offset voltage Maximum output voltage Output offset voltage Maximum output voltage Voltage gain Input offset voltage Output high level voltage Output low level voltage Output saturation voltage 1 Output saturation voltage 2 VSATL1 0.7 1.1 1.6 V V dB Upper+Lower IL=200mA Upper+Lower IL=500mA 1.55 VSATL2 1.0 2.3 9.2 Output "H" voltage gain GVH 7.4 11.0 * This product is not designed for protection against radioactive rays.
