NAME
FUNCTION
1
I/O1
General-Purpose Open-Drain Logic Input/Output 1. I/O1 is intended for driving LEDs, driving power-plane
switching MOSFETs, or detecting fan presence or chassis intrusion.
2
I/O2
General-Purpose Open-Drain Logic Input/Output 2. I/O2 is intended for driving LEDs, driving power-plane
switching MOSFETs, or detecting fan presence or chassis intrusion.
PIN
3
ADD0
SMBus Address Select Pin 0. See Table 11.
4
ADD1
SMBus Address Select Pin 1. See Table 11.
8
DXP
Combined Current Source and ADC Positive Input from Remote Diode. Place a 2200pF capacitor
between DXP and DXN for noise filtering.
7
DXN
Combined Current Sink and ADC Negative Input from Remote Diode. DXN is normally biased to a diode
voltage above ground.
6
AGND
Analog Ground
5
ADD2
SMBus Address Select Pin 2. See Table 11.
13
SMBCLK
SMBus Serial-Clock Input

10
SYNC
Oscillator Synchronization Input. Connect to AGND to use internal clock. Capture range is 140kHz to
400kHz. The synchronization signal is internally applied to the FAN PWM clock. See Table 5 for synchro-
nized frequencies.
9
