4-channel BTL driver for CD players
BA5941FP
The BA5941FP contains a 4-channel BTL driver for CD player motors and actuators. Perfect for compact applications with the use of the HSOP 28-pin package. FApplications CD players, CD-ROM FFeatures 1) 4-channel BTL driver. 2) Perfect for compact applications with the use of the HSOP 28-pin power package. 3) Wide dynamic range (4.8V (Typ.) when VCC = 8V and RL = 8Ω). FAbsolute maximum ratings (Ta = 25_C)

FOperation notes (1) The BA5941FP contains a thermal shutdown circuit. When the chip temperature reaches 175_C (Typ.), the output current is muted. (2) By having the mute pin (pin 9) voltage open or lowered to 0.5V or below, the output currents can be muted. For normal conditions, have the voltage at pin 9 pull-up to 2V. (3) If the voltage...
