General Description

The MAX6654 evaluation system (EV system) consists

of a MAX6654 evaluation kit (EV kit) and a companion

system management bus (SMBus™) interface board.

The MAX6654 EV kit is an assembled and tested PC

board that demonstrates the MAX6654 temperature

sensor. It monitors both the junction temperature of the

MAX6654 and the temperature of an external diode-

connected transistor, and converts the temperature to

8-bit or 11-bit (extended resolution mode), 2-wire serial

data. A 2N3906 temperature-sensor transistor comes

soldered to the board in a SOT23 package, but it can

be removed. The board can then be connected through

a twisted pair to a remote diode close to your system.

The Maxim SMBus interface board (MAXSMBUS)

allows an IBM-compatible PC to use its parallel port to

95/98/2000-compatible software provides a user-friend-

ly interface to exercise the features of the MAX6654.

The program is menu driven and offers a graphic inter-

face with control buttons and status display.

Order the MAX6654EVSYS for a complete IBM PC-

based evaluation of the MAX6654. Order the

MAX6654EVKIT if you already have an SMBus inter-

face.
