BA6795FP

Optical disc ICs 5-channel BTL driver for CD players BA6795FP The BA6795FP is a 5-channel BTL power driver for CD players and has an internal 5V regulator (attached PNP transistor required). The loading and spindle motor output pins are dual-use output pins and are switched between drivers using a control input. In addition, the internal level shifting circuit reduces the number of external components. FApplications CD players, CD-ROM drives and other optical disc devices FFeatures 1) 5-channel BTL driver in a HSOP 28-pin package, ideal for application miniaturization. 2) Internal level shifting circuit reduces the number of external components. FAbsolute maximum ratings (Ta = 25_C) 3) Gain is adjustable with an attached resistor. 4) Internal thermal shutdown circuit. 5) Internal 5V regulator.
