... Optical disc ICs 4-channel BTL driver for CD players BA5934FP The BA5934FP is a 4-channel BTL driver developed to drive CD player motors and actuators. Perfect for compact ap- plications with the use of the HSOP 28-pin power package. FApplications CD players, CD-ROM FFeatures 1) In addition to internal drivers for the focus coil, track- ing coil, and sled motor, it also contains a driver for the loading motor ...

... Optical disc ICs FOperation notes (1) The BA5934FP contains a thermal shutdown cir- cuit. When the chip temperature reaches 175_C (Typ.), the output current is muted. (3) If the voltage of the bias pin (pin 23) drops below 1.4V (Typ.), outputs are muted. For normal conditions, have the voltage above 1.6V and below 6.5V. ...
