BA5944FP

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.
