| 99W119A 5 Channel Driver for CD/CD-ROM BA5811FM Description The BA5811FM is 5-channel driver including 4-channel BTL drivers and 1-channel reversible motor driver for CD/CD-ROM applications. Separating Vcc into Pre and Pow can make the power more efficient. A power-saving mode is enabled by a power-save terminal. Dimension(Units : mm) Features 1) Small surface mounting power package HSOP-M28 2) Thermal shut down circuit built-in 3) Wide dynamic range (4.0V typical at PREVCC=12V, POWVCC=5V) 4) 4-channel BTL driver (2-channel is able to be used for a stepping motor) 5) The output voltage is adjustable by the voltage control terminal.
