DESCRIPTION
FETs in the output stage lower the saturation voltage and power consumption as compared with conventional drivers
using bipolar transistors.
when the supply voltage drops. A 30-pin plastic shrink SOP package is adopted to help create compact and slim
application sets.
three channels for driving sled motors and tilt control, and another channel for driving loading motor are provided,
making the product ideal for applications in DVD-ROM/DVD-RAM.
