Optical disc ICs
4-channel BTL driver for CD players
BA6790FP / BA6791FP
The BA6790FP and BA6791FP are 4-channel BTL drivers for CD player actuators and motors. These ICs have internal
5 V regulators and general purpose operational amplifiers, and are mounted to a 28-pin HSOP package, allowing for
the miniaturization of applications.
