5-channel BTL driver for CD and MD Players
BA6996FP
The BA6996FP, an IC designed for CD and MD players, has a 5-channel BTL power driver and a standard operational amplifier. The spindle and tray driver share a single output buffer, and are specified with a control pin. In addition, the internal level shift circuit reduces the number of attached components. FApplications CD players, CD-ROM drives, MD players and other optical disc devices FFeatures 1) A 5-channel BTL driver in a HSOP 28-pin package, allowing for application miniaturization. 2) Five drivers are turned on and off according to the combination of control pin logic. 3) The tray driver operates even when the servo power supply drops.
