______

THERM/ADDR

OD

During the power-up, the device selects SMBus (or I2C) address based on

the pull-up resistor. During the normal operation, this pin will be asserted to

indicate a Therm Limit exceeding event, requiring a pull-up resistor

Active low digital

_____

ALERT output signal, requiring a pull-up resistor

7

SMDATA

DIOD

SMBus data input/output, requiring pull-up resistor

8

SMCLK

DI

SMBus clock input, requiring pull-up resistor

Not internally connected, but recommend grounding.

Table 2. Pin types

Pin Type

Description

Power

This pin is used to supply power or ground to the device.

AIO

Analog input/output. This pin is used as an I/O for analog signals.

DI

Digital input. This pin is used as a digital input. This pin is 5 V tolerant.

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 5 V 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 5 V tolerant.
