Pin Function
+12V Switched Supply (Output): Load carrying output.
3.3V Gate Drive (Output): Drives gate of external N-channel MOSFET +3V
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.)
+3.3V Output Voltage Sense (Input): Connect to source of external
N-channel MOSFET (+3V switched output) to monitor for output undervolt-
age conditions.
+3.3V Current Sense (Input): Measures voltage drop across an external
sense resistor with respect to 3VIN for overcurrent detection through the
+3.3V switch.
3V Supply (Input): +3.3V-supply input for current monitoring (reference input
for 3VSENSE). Not a load-current carrying input.
PCI-Bus Reset (Input): Input from PCI bus that resets the internal logic.
