MAX6660 Evaluation System/Evaluation Kit
General Description
The MAX6660 evaluation system (EV system) consists of a
MAX6660 evaluation kit (EV kit) and a companion Maxim
System Management Bus (SMBus)鈩?interface board.
The MAX6660 EV kit is an assembled and tested PC
board that demonstrates the MAX6660 remote temper-
ature sensor and fan-speed regulator. It monitors the
junction 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 MAX6660 also incorporates a closed-loop fan con-
troller that regulates fan speed with tachometer feed-
back.
Note:
Use this EV kit data sheet in conjunction
with the MAX6660 data sheet.
The Maxim SMBus interface board (MAXSMBUS)
allows an IBM-compatible PC to use its parallel port to
emulate an SMBus 2-wire interface. Windows庐
95/98/2000-compatible software provides a user-friend-
ly interface to exercise the features of the MAX6660.
The program is menu driven and offers a graphic inter-
face with control buttons and status display. (Note:
Windows 2000 requires the installation of a driver; refer
to Win2000.pdf or Win2000.txt located on the diskette.)
Order the MAX6660EVSYS for a complete IBM PC-based
evaluation of the MAX6660. Order the MAX6660EVKIT if
you already have an SMBus interface.
