Type Description
Number Name(s) Structure
Interrupt Input Bar. This is an active low input that
1 INT_IN Digital Input propagates the INT_IN signal to the INT output of the
LM96080.
2 SDA Digital I/O Serial Bus Bidirectional Data. NMOS open-drain output.
3 SCL Digital Input Serial Bus Clock.
4-5 FAN1, FAN2 Digital Inputs Fan tachometer inputs.
Board Temperature Interrupt driven by Overtemperature
6 BTI Digital Input Shutdown (O.S.) outputs of additional temperature sensors
such as LM75. This pin provides internal pull-up of 10 kΩ.
General Purpose Input pin. GPI can be used as an
GPI (Chassis additional active high interrupt input pin or as an active high
7 Digital I/O
Intrusion) input from an external circuit which latches a Chassis
Intrusion event.
8 GND GROUND Internally connected to all of the digital circuitry.
+3.0V to +5.5V power. Bypass with the parallel combination
9 V
+
POWER of 10 μF (electrolytic or tantalum) and 0.1 μF (ceramic)
bypass capacitors.
Non-Maskable Interrupt (Active High, PMOS, open-drain) or
Interrupt Request (Active Low, NMOS, open-drain).
10 INT Digital Output
Whenever INT_IN, BTI, or GPI interrupts, this output pin
becomes active.
General Purpose Output pin is an active low NMOS open
GPO (Power
