Functional Pin Description
5VSB (Pin 1)
Provide a 5V bias supply for the IC to this pin by connecting
it to the ATX 5VSB output. This pin also provides the base
bias current for all the external NPN transistors controlled by
the IC. The voltage at this pin is monitored for power-on
reset (POR) purposes.
EN3VDL and EN5VDL (Pins 2 and 5)
These pins control the logic governing the output behavior in
response to S3 and S4/S5 requests. These are digital inputs
whose status can only be changed during active states
operation or during chip shutdown (SS pin grounded by
external open-drain device). The input information is
latched-in when entering a sleep state, as well as following
5VSB POR release or exit from shutdown.
GND (Pin 8)
Signal ground for the IC. All voltage levels are measured
with respect to this pin.
FAULT/MSEL (Pin 9)
This is a multiplexed function pin allowing the setting of the
memory output voltage to either 2.5V or 3.3V (for RDRAM or
SDRAM memory systems). The memory voltage setting is
latched-in 3ms (typically) after 5VSB POR release. In case
of an under-voltage on any of the outputs or an over-
temperature event, this pin is used to report the fault
condition by being pulled to 5VSB.
S3 and S5 (Pins 6 and 7)
These pins switch the IC’s operating state from active (S0,
S1) to S3 and S4/S5 sleep states. Connect S3 to SLP_S3
and S5 to SLP_S5. These are digital inputs featuring internal
70k (typical) resistor pull-ups to 5VSB. Internal circuitry de-
glitches the S3 pin for disturbances. Additional circuitry
blocks any illegal state transitions (such as S3 to S4/S5 or
vice versa). When entering an S4/S5 sleep state, the S3
signal is allowed to go low as far as 200s (typically) ahead
of the S5 signal.
SS (Pin 13)
Connect a small ceramic capacitor (allowable range: 5nF-
0.22F; 0.1F recommended) from this pin to GND. The
internal Soft-Start (SS) current source along with the
external capacitor creates a voltage ramp used to control the
ramp-up of the output voltages. Pulling this pin low with an
open-drain device shuts down all the outputs as well as
