O2Micro OZ998

the OZ998 can be configured to support two different power planes with different sets of General Purpose Input/Output (GPIO) signals, which supplements and enhances the power management capability of the chipsets, commonly found in an ACPI (Advanced Configuration of Power Interface) subsystem. The OZ998 is packaged in a low profile, small 28 pin SSOP.
