BTL Driver IC for CD-ROM

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.

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.
