Table 3. PIN FUNCTION DESCRIPTIONS
Pin No.
Mnemonic
Description
1
DRIVE1
Open Drain Digital Output. Pulsewidth Modulated (PWM) output to control the speed of Fan 1.
Requires 10 kW typical pull-up resistor.
2
FAULT1
Open Drain Digital I/O. When used with a fan having a fault output, a Logic 0 input to this pin signals a
fault on Fan 1. Also used as a fault output.
3
TACH1
Open Drain Digital Input. Digital fan tachometer input for Fan 1. Will accept logic signals up to 5 V even
when VCC is lower than 5 V.
4
PRESENT1
Open Drain Digital Input. A shorting link in the fan connector holds this pin low when Fan 1 is
connected.
5
SCL
Open Drain Digital Input. Serial Bus Clock. Requires 2.2 kW pull-up typical.
6
SDA
Digital I/O. Serial Bus bidirectional data. Open-drain output requires 2.2 kW pull-up.
7
GND
System Ground
8
V
CC
Power (3.0 V to 5.5 V). Typically powered from 3.3 V power rail. Bypass with the parallel combination of
10 mF (electrolytic or tantalum) and 0.1 mF (ceramic) bypass capacitors.
9
CFAULT
Open Drain Digital I/O. Cascade fault input/output used for fault signaling between multiple ADM1029s.
10
INT
Digital Output. Interrupt Request (Open Drain). The output is enabled when Bit 1 of the Configuration
Register is set to 0. The default state is enabled.
11
GPIO2
Open Drain Digital I/O. General-purpose logic I/O pin.
12
RESET
Open Drain Digital Input. Active low reset input.
13
D1/GPIO3
Analog Input/Open Drain Digital I/O. Connected to cathode of external temperature-sensing diode, or
may be reconfigured as a general-purpose logic input/output.
14
D1+/GPIO4
Analog Input/Open Drain Digital I/O. Connected to anode of external temperature-sensing diode, or
may be reconfigured as a general-purpose logic input/output.
15
ADD
Eight-level Analog Input. Used to set the three LSBs of the serial bus address.
16
D2/GPIO5
Analog Input/Open Drain Digital I/O. Connected to cathode of external temperature-sensing diode, or
may be reconfigured as a general-purpose logic input/output.
17
D2+/GPIO6
Analog Input/Open Drain Digital I/O. Connected to anode of external temperature-sensing diode, or
may be reconfigured as a general-purpose logic input/output.
18
TMIN/INSTALL
Eight-level Analog Input. The voltage on this pin defines whether automatic fan speed control is
enabled, the minimum temperature at which the fan(s) will turn on in automatic speed control mode,
and the number of fans that should be installed.
19
AIN0/GPIO0
Analog Input/Open Drain Digital I/O. May be configured as a 0 V to 2.5 V analog input or as a
general-purpose digital I/O pin.
20
AIN1/GPIO1
Analog Input/Open Drain Digital I/O. May be configured as a 0 V to 2.5 V analog input or as a
general-purpose digital I/O pin.
21
PRESENT2
Open Drain Digital Input. A shorting link in the fan connector holds this pin low when Fan 2 is
connected.
22
TACH2
Open Drain Digital Input. Digital fan tachometer input for Fan 2. Will accept logic signals up to 5 V even
when V
CC
 is lower than 5 V.
23
FAULT2
Open Drain Digital I/O. When used with a fan having a fault output, a Logic 0 input to this pin signals a
fault on Fan 2. Also used as a fault output.
24
DRIVE2
Open Drain Digital Output. Pulsewidth Modulated (PWM) output to control the speed of Fan 2.
Requires 10 kW typical pull-up resistor.
