DESIGNATOR
FUNCTION
DESCRIPTION
15, 28
M12VIN
-12V Input
-12V Supply Input. Also provides power to the -12V overcurrent circuitry.
4, 11
FLTN
Fault Output
5V CMOS Fault Output; LOW = FAULT. An optional capacitor may be place from this pin to
ground to provide additional immunity from power supply glitches.
20, 23
3V5VG
3.3V/5V Gate Output
Drive the gates of the 3.3V and 5V MOSFETs. Connect a capacitor to ground to set the
start-up ramp. During turn on, this capacitor is charged with a 25
μ
A current source.
UV comparator disabled when this pin below 9.6V nominal.
21, 22
12VIN
12V Input
12V supply input for IC and 12VO. Both 12VIns to be connected to a single +12V supply.
16, 27
3VISEN
3.3V Current Sense
Connect to the load side of the current sense resistor in series with source of external 3.3V
MOSFET.
17, 26
3VS
3.3V Source
Connect to source of 3.3V MOSFET. This connection along with (3VISEN) senses the
voltage drop across the sense resistor.
19, 24
5VS
5V Source
Connect to source of 5V MOSFET switch. This connection along with (5VISEN) senses the
voltage drop across the sense resistor.
18, 25
5VISEN
5V Current Sense
Connect to the load side of the current sense resistor in series with source of external 5V
MOSFET.
3, 12
PWRON
Power On Control
Controls all four switches. High to turn switches ON, Low to turn them OFF.
6, 9
12VG
Gate of Internal PMOS Connect a capacitor between 12VG and 12VO to set the start-up ramp for the +12V supply.
This capacitor is charged with a 25
μ
A current source during start-up.
UV comparator disabled when this pin >1.4Vnominal.
7, 8
12VO
Switched 12V Output
Switched 12V output. Rated for 0.5A.
2, 13
M12VG
Gate of Internal NMOS Connect a capacitor between M12VG and M12VO to set the start-up ramp for the M12V
supply. This capacitor is charged with 25
μ
A during start-up.
1, 14
M12VO
Switched -12V
Output
Switched 12V Output. Rated for 100mA.
10
OCSET
Overcurrent Set
Connect a resistor from this pin to ground to set the overcurrent trip point of all eight
switches. All eight over current trips can be programmed by changing the value of this
resistor. The default (6.04k
, 1%) is compatible with the maximum allowable currents as
outlined in the PCI specification.
5
VSS
Ground
Connect to common of power supplies.
