MAX6639EVKIT+ Datasheet PDF - Maxim Integrated

●Assembled and tested MAX6639 evaluation kit (EV kit) used to evaluate the MAX6639 dual temperature sensor/fan controller. The MAX6639 monitors its own die temperature and the junction temperature of one external diode-connected transistor or the junction temperatures of two external diode-connected transistors. It converts the temperature to 8bit or 11bit 2-wire serial data that can be accessed over a 2-wire serial bus. The MAX6639 EV kit includes both external diode-connected transistors (2N3906) soldered to the board which can be bypassed to connect the board through a twisted pair to remote diodes close to system. Suitable for use in desktop computers, networking equipment, notebook computers, projectors and servers.
