HIP6503 Application Circuit

Figure 12 shows an application circuit of an

ACPI-sanctioned power management system for a

microprocessor computer system. The power supply

+5VSB, +5V, and +12VDC ATX supply outputs. Q4 can also

be a PNP, such as an MMBT2907AL. For detailed

information on the circuit, including a Bill-of-Materials and

circuit board description, see Application Note AN9901.
