Recommended Operating Conditions
The BA5944FP is a BTL driver IC (actuator operation)
developed for CD-ROMs. Two highly accurate 3.6V
regulators and a 4.2V reset circuit that acts as a
peripheral power supply are included, as well as two
general purpose comparators. An achievement in
space savings of the set and reducing components
has been realized by integrating regulators and drivers
into an actuator driver IC as one chip.
