Pin Number
Pin Name
Pin Function
7
/LPCIRST
Local PCI Reset (Open-Drain Output): Local PCI reset output to PCI
controller. Compliant to CompactPCI specification for LOCAL_PCI_RESET.
8
/EPWRGD
Early Power Good (Open-Drain Output): This signal goes active should
/FAULT or /PWRGD go active. No deglitch filtering is provided. This signal
satisfies PCI /RST timing for T
FAIL
per PCI Local Bus Specification, ver-
sion 2.1.
9
/PWRGD
Power Good (Open-Drain Output): Active-low output goes active when all
supplies are within tolerance. (A 20
μ
s delay is inserted prior to activation to
reduce nuisance tripping.)
10
VPCHG
Precharge Supply (Output): (MIC2580-1.0) +1V
±
20% supply used for
precharge bias for I/O terminations (CompactPCI only).
11
GND
Ground
12
M12VIN
–
12V Supply (Input): Input for internal
–
12V switch.
13
M12VOUT
–
12V Switched Supply (Output): Switched
–
12V supply to PCI Hot Plug
compliant socket. Load carrying output.
14
/ON
On-Off Control (Input): Logic low turns on all switches; logic high turns off all
switches. Also used to reset the device from a circuit breaker condition.
15
CRST
Reset Delay (External Component): Connect to external capactior (C
RST
) to
increase power-on reset delay.
16
/POR
Reset (Open-Drain Output): Active-low signal remains active for a time
determined by C
RST
after all supplies are within tolerance; i.e., /PWRGD is
active. This signal may be used as a reset for logic controllers.
17
CSLEW
Slew (External Component): Connect to external capacitor (C
SLEW
) to
program the output slew rate of 3VGATE, 5VGATE, 12VGATE (internal) and
M12VGATE (internal).
18
CSTART
Start-Up Timer (External Component): Connect to external capacitor
(C
START
) to increase the filter delay used to gate the /FAULT output upon
start-up. Used to prevent nuisance tripping during turn-on of supplies.
19
/FAULT
Fault (Open-Drain Output/Input): This active-low output signal activated
upon overcurrent or thermal shutdown. Includes 20
μ
s deglitch filter. Fault is
reset using /ON.
Forcing pin low turns off all switches but does not activate the circuit breaker
function.
20
5VIN
5V Supply (Input): +5V-supply input for current monitoring (reference
voltage for 5VSENSE). Not a load-current carrying input.
21
5VSENSE
+5V Current Sense (Input): Measures voltage drop across an external
sense resistor with respect to 5VIN for overcurrent detection through the +5V
switch.
22
5VOUT
+5V Output Voltage Sense (Input): Connect to source of external N-channel
MOSFET (+5V switched output) to monitor for output undervoltage condi-
tions.
23
5VGATE
5V Gate Drive (Output): Drives gate of external N-channel MOSFET +5V
switch. Adding capacitance will slow the slew rate of the external MOSFET
switch turn-on. (The external MOSFET
’
s gate is charged by an internal
current source.)
24
12VIN
12V Supply (Input): MIC2580 power supply and input for internal +12
switch. Supplies power for internal circuitry.
