BTL Driver IC for CD-ROM
BA5944FP
Description
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.
Features
1) 2-channel dynamic range actuator driver built-in
2) Highly accurate (+/ 2%) 3.6V regulator 2-channel
built-in (1-channel regulator can be controlled with
On/Off switch.)
3) Highly accurate (+/ 2%) 4.2V reset curcuit built-in
4) Includes two general purpose comparators.
