The Advanced Configuration and Power Interface
specification (ACPI; [1]), written by a consortium
representing Intel, Microsoft and Toshiba, attempts to evolve
the current collection of power management methods and
configuration interfaces into a well-specified and unified
power management and configuration mechanism. The key
objective in the ACPI specification is to transfer all control of
power management and configuration functions to the
operating system, thus enabling Operating System Directed
Power Management (OSPM). ACPI-compliant systems will
benefit from a robust interface for configuring motherboard
devices, a versatile power management interface enabling a
wide variety of solutions with full operating-system support,
and not lastly, a realm of new, intelligent possibilities added
to the already broad span of PC uses.
Ensuring that the supply is not plugged into the mains, or
that the AC switch is off (if provided), connect the main ATX
output connector to J1.
‰ Connect the Output Loads
Connect typical standby loads to all the evaluation board’s
outputs. Consult Table 1 for maximum loads supported by
the design of the HIP6500B/02BEVAL1 in the configuration
received; consult the ‘HIP6500B/02BEVAL1 Modifications’
chapter for information on modifying the evaluation board to
meet your special needs.
‰ Set Start-Up State (Active Is Recommended)
If start-up in active state (S0/S1/S2) is desired, ensure both
‘S3’ (SW2) and ‘S5’ (SW3) switches are in the off position
(away from ‘S3’ or ‘S5’ marking). Ensure the ‘ATX ON’

Quick Start Evaluation
Important!
Given the specialized nature of the HIP6500B and
HIP6502B, the HIP6500B/02BEVAL1 boards are meant to
be evaluated only with an ATX power supply. Furthermore,
only an ACPI-ready ATX supply can be used to power-up
the evaluation boards (720mA capability on 5VSB output;
ATX Specification v2.02, [4]). Standard laboratory power
supplies are not suitable for powering up this evaluation
board.
Circuit Setup
‰ Set Up JP1, JP2, and JP2, JP3
Before connecting the input ATX supply to the
HIP6500B/02BEVAL1 board, consult the circuit schematic
and data sheets and set the JP1 and JP2 configuration
jumpers on the HIP6500BEVAL1, and JP2 and JP3 jumpers
on the HIP6502BEVAL1 according to the configuration you
wish to emulate. These particular configurations are latched
in during certain times, but can be subsequently changed at
on the switch with that name - the signal conditioning
circuitry ensures correct S3 and S5 pin stimulation.
Operation
‰ Provide Bias Voltage to the Board
Plug the ATX supply into the mains. If the supply has an AC
switch, turn it on. The ‘5VSB’ (LP4) LED should light up,
indicating the presence of 5V standby voltage on board.
‰ Examine Start-Up Waveforms
Sleep state start-up is immediate following application of
bias voltage. Using an oscilloscope or other laboratory
equipment, you may study the ramp-up and/or regulation of
the controlled voltages, according to the specific JP1/JP2, or
JP2/JP3 configuration previously set and the specific
standby state selected.
For start-up into an active state (standby switches set off
prior to application of bias voltage), flip on the ‘ATX ON’
switch (SW1). This will turn on the main ATX outputs and the
HIP6500B/02B will start up into active state. Once turned on,
SW1 needs not be turned off until bias is removed from the
board.
‰ Examine Output Quality Under Varying Loads
In either state (sleep or active) vary the output loads to
simulate computer loads typical of the specific operating
state the circuit is in.
certain times. See HIP6500B/02B data sheets for
information on the available configurations and how to set
them.
