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 kΩ 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 kΩ pull-up typical.

6

SDA

Digital I/O. Serial Bus bidirectional data. Open-drain output requires 2.2 kΩ pull-up.

7

GND

System Ground

8

VCC

Power (3.0 V to 5.5 V). Typically powered from 3.3 V power rail. Bypass with the parallel

combination of 10 µF (electrolytic or tantalum) and 0.1 µF (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 con-

trol 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 VCC 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 kΩ typical pull-up resistor.
