MAX1617 Temperature Sensor Evaluation Kit

Active: In Production.

The MAX1617 evaluation kit (EV kit) is a demonstration platform for the MAX1617 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 via 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 MAX883 linear regulator with reverse voltage protection steps down the unregulated DC input to 5V to power the glue logic, the MAX1617, and the SMBus pull-up resistors.

The software runs under Windows® 3.1 or 95. This user-friendly program is menu-driven and offers a graphic user interface with control buttons and numeric data displays.
