Triple Linear Power Controller with ACPI Control Interface
The HIP6501A, paired with either the HIP6020 or HIP6021,
simplifies the implementation of ACPI-compliant designs in
microprocessor and computer applications. The IC
integrates two linear controllers and a low-current pass
transistor, as well as the monitoring and control functions
into a 16-pin SOIC package. One linear controller generates

The HIP6501A’s operating mode (active-state outputs or
sleep-state outputs) is selectable through two control pins:
S3 and S5. Further control of the logic governing activation
of different power modes is offered through two enabling
