10 Maxim Integrated

Evaluates: MAX6581

MAX6581 Evaluation Kit

Advanced User Interface

There are two methods for communicating with the

device: through the normal user-interface main window

or through the SMBus/I²C commands available by select-

ing Options | Interface (Advanced Users) from the

menu bar. An Advanced User Interface window pops

up with the 2-wire interface tab selected, which allows

the SMBus/I

C-compatible protocols, such as read byte

and write byte, to be executed. The only SMBus/I

C-

compatible protocols used by the device are:

1 - SMBusWriteByte(addr,cmd,data8)

4 - SMBusReadByte(addr,cmd) → data8

The combo and edit boxes accept numeric data in hexa-

decimal and should be prefixed by 0x. See Figure 3 for

an example of this tool.

In this example, the software is reading from Device

Address 10011010 r/w (binary), and register address

0x07.

Detailed Description of Hardware

The MAX6581 EV kit is an assembled and tested PCB

used to evaluate the MAX6581 8-channel temperature

sensor. The device monitors its own die temperature and

the temperatures of up to seven external diode-connect-

ed transistors. The EV kit features an on-board microcon-

troller that receives commands from a PC through the

USB port. The EV kit can be powered directly from the

USB or from a 3.3V single-supply voltage.
