PIN DESCRIPTIONS
The description of the pins is listed in Table 3-1.
All pins labeled with (5V) are 5V tolerant.
For the 5V tolerant pins that have a pull-up resistor, the
voltage difference between VDD and the pull-up voltage
must never exceed 3.6V
The pin types are described in Table 3-2.

OD (5V)
ALERT - Open drain I/O operates as active low interrupt or TACH
input; requires pull-up resistor, which defines auto-configuration
mode (see Table 4-1).
DI (5V)
TACH - TACH input
7
SMDATA
DIOD Output (5V) SMBus Data input/output
8
SMCLK
DIOD Output (5V) SMBus Clock input
TABLE 3-2:
PIN TYPES
Power
This pin is used to supply power or ground to the device
DI
Digital Input. This pin is used as a digital input and is 5V tolerant
AI
Analog Input. This pin is used as an input for analog signals
AO
Analog Output. This pin is used as an output for analog signals
DIOD
Digital Input/Open Drain Output. This pin is used as a digital I/O. When it is used as an
output, it is open drain and requires a pull-up resistor. This pin is 5V tolerant.
OD
Open Drain Digital Output. This pin is used as a digital output. It is open drain and requires
a pull-up resistor. This pin is 5V tolerant.
