3-channel BTL driver for CD, CD-ROM,
DVD, and DVD-ROM
BA5973FP
The BA5973FP is a 3-channel BTL driver developed for use as the actuator and loading motor driver for CD and DVD
players. Since the gain and frequency characteristics for the actuator can be set to any desired value with external com-
ponents, it is can be used in a wide range of applications.
FFeatures
1) 3-channel BTL driver for CD players.
2) The HSOP-28 package allows for the design of
smaller sets.
