说明 The MAX1617A evaluation kit (EV kit) is a demonstration platform for the MAX1617A temperature-sensor IC. It monitors both the junction temperature of the IC and the temperature of a remote (external) diode-connected transistor, and converts these temperatures to 8-bit, 2-wire serial data. A 2N3904 remote temperature-sensor transistor comes soldered to the board in a SOT23 package, but for more realistic experiments, it can easily be removed and connected through a twisted pair to the DXP and DXN terminals.
The EV kit is designed to be connected to a standard IBM®-compatible PC parallel printer port. Signals from the parallel port are converted to open-drain SMBus clock and data by a 74HC05 logic chip on the board. An on-board MAX1615 linear regulator steps down the unregulated DC input to 5V to power the glue logic, the MAX1617A, and the SMBus pullup resistors.
The software runs under Windows® 95, 98, or 2000. This user-friendly program is menu-driven and offers a graphic user interface with control buttons and numeric data displays. Note: Windows 2000 requires the installation of a driver; refer to Win2000.pdf or Win2000.txt located on the diskette.
