MAX6654 Evaluation System
General Description
The MAX6654 evaluation system (EV system) consists
of a MAX6654 evaluation kit (EV kit) and a companion
system management bus (SMBus鈩? 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
emulate an Intel SMBus 2-wire interface. Windows
廬
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.
