4-channel BTL driver for CD players
BA6897S / BA6897FP
The BA6897S and BA6897FP are a 4-channel BTL driver for CD player motors and actuators.
It has an internal 5V
regulator and standard operational amplifier, and is suited to a wide range of applications.
FApplications CD players, CD-ROM drives FFeatures 1) Minimal number of external components.
2) Driver gain is adjustable with just one attached resistor.
3) Internal 5V
regulator (attached
PNP transistor necessary).
4) Internal standard operational amplifier.
5) Internal thermal shutdown circuit.
FAbsolute maximum ratings (Ta = 25_C)
