General Description The MAX6639 evaluation kit (EV kit) is an assembled and tested PCB used to evaluate the MAX6639 dual tempera- ture sensor/fan controller. The MAX6639 monitors its own die temperature and the junction temperature of one external diode-connected transistor, or the junction tem- peratures of two external diode-connected transistors. It converts the temperature to 8-bit or 11-bit 2-wire serial data that can be accessed over a 2-wire serial bus. The MAX6639 EV kit includes both external diode-connect- ed transistors (2N3906) soldered to the board, which can be bypassed to connect the board through a twisted pair to remote diodes close to your system. The temperature data is also used by the internal dual PWM fan-speed controller to adjust the speed of up to two cooling fans. Speed control is accomplished by tachometer feedback from the fan. The EV kit also includes Windows® 2000/XP- and Windows Vista®-compatible software, which provides a simple user interface for exercising the features of the MAX6639. The program is menu-driven and offers a graphical user interface (GUI) complete with control but- tons. The EV kit comes with the MAX6639AEE+ installed. Contact the factory for free samples of the pin-compatible MAX6639FAEE+ and MAX6640AEE+. The MAX6639 EV kit also evaluates the MAX6640. The MAX6640 is not recommended for new designs.
