BA5912AFP-Y

Optical disc ICs 2-channel BTL driver for CD players BA5912AFP-Y The BA5912AFP-Y is a 2-channel BTL driver developed to drive CD player motors and actuators. Perfect for compact applications with the use of the HSOP 25-pin package. FApplications CD players, CD-ROM FFeatures 1) 2-channel BTL driver. 2) Perfect for compact applications with the use of the HSOP 25-pin power package. 3) Wide dynamic range. 4) External mute pin enables the muting of the output current (independent muting for channels 1 and 2). Muting both channels causes the IC to enter the standby mode. 5) Two internal multi-purpose operational amplifiers. 6) Power supply is divided into three systems (Pre VCC, Pow VCC for channel 1, and Pow VCC for channel 2) 7) Internal standard two operational amplifier. 8) Internal thermal shutdown circuit.
