6-channel BTL driver for CD players
BA5936S
The BA5936S is a 6-channel BTL driver developed for use as the sled motor, spindle motor, actuator, and loading motor driver for CD players. It contains a current limiting function and 5V
regulator for compatibility in a wide range of applications. FApplications CD players FFeatures 1) 6-channel BTL driver for CD players. Contains 4 channels for the focus coil, tracking coil, sled motor, and spindle motor drives; and 2 channels for the loading motor driver. 2) Internal 5V
regulator with a earth protection circuit (requires an external
PNP transistor). FAbsolute maximum ratings (Ta = 25_C)
3) Internal mute circuit (enables the muting of the driver outputs from all but the loading driver, and muting of the
regulator output). 4) Internal thermal shutdown circuit.
FRecommended operating conditions (Ta = 25_C)
