Product details
Overview
The MAX6639EVKIT+ from Maxim Integrated is a fully assembled and tested evaluation kit designed to characterize the MAX6639 dual temperature sensor and dual PWM fan controller IC. It integrates on-board 2N3906 remote diode transistors, USB-to-PC interface via FTDI UART bridge, Windows-compatible GUI software, and configurable jumpers for SMBus/I²C address, power source, and fan tachometer pull-up selection. It supports 8-bit (1°C/LSB) and 11-bit (0.125°C/LSB) temperature resolution, dual-channel thermal monitoring, and programmable fan control up to 25kHz PWM frequency.
For engineers reviewing the MAX6639EVKIT+ datasheet, MAX6639EVKIT+ pinout, MAX6639EVKIT+ application, or MAX6639EVKIT+ equivalent, this kit enables rapid validation of thermal management subsystems in server, telecom, and industrial embedded systems - especially where local + remote diode temperature sensing, tachometer-based closed-loop fan speed control, and SMBus/I²C register-level configuration are required.
Technical Context
The MAX6639EVKIT+ implements a complete hardware-software evaluation platform centered on the MAX6639AEE+ IC (16-pin QSOP), which monitors two temperature channels - internal die and one or two external diode-connected transistors - with selectable 8-bit or 11-bit resolution. Its onboard MAXQ2000-RAX+ microcontroller generates SMBus/I²C commands, while the FT245RL UART-to-USB converter enables Windows host communication.
Hardware configurability includes jumper-selectable SMBus slave address (0x58/0x5C/0x5E), 3-wire vs. 4-wire fan tachometer pull-up voltage (VFAN or VIN), and local/remote channel assignment for fan control. The kit ships with pre-soldered 2N3906 transistors and supports connection to user-supplied DC fans (≤1.4A, ≤30V) with tachometer outputs.

FAQ
What does the MAX6639EVKIT+ evaluate?
The MAX6639EVKIT+ evaluates the MAX6639AEE+ dual temperature sensor and fan controller IC, including its full register set, SMBus/I²C communication, dual-channel thermal measurement (local die + one or two remote diodes), and dual PWM fan drive with tachometer feedback. It also supports evaluation of the pin-compatible MAX6639F and MAX6640 variants, though the MAX6640 is not recommended for new designs.
Does the MAX6639EVKIT+ require external power for fans?
Yes, the MAX6639EVKIT+ requires an external power supply connected to the VFAN and FAN_GND pads to drive connected DC fans. The voltage must be between 3.0V and 30V, and each fan must draw no more than 1.4A continuous. The board itself is powered via USB; only fan motors need external voltage.
How is SMBus/I²C address configured on the MAX6639EVKIT+?
The SMBus/I²C slave address of the MAX6639AEE+ on the MAX6639EVKIT+ is set using jumper JU5: position 1–2 yields address 0x5E, open yields 0x5C, and position 2–3 yields 0x58. This matches the ADD pin logic of the MAX6639 IC and allows coexistence of multiple devices on the same bus without address conflict.
Can the MAX6639EVKIT+ support both 3-wire and 4-wire fans?
Yes, the MAX6639EVKIT+ supports both configurations via jumpers JU6 and JU7. For 3-wire fans, install shunts in positions 1–2 to pull up TACH1/TACH2 to VFAN; for 4-wire fans, use positions 2–3 to pull up to VIN. This ensures correct tachometer signal interpretation regardless of fan type.
What software is included with the MAX6639EVKIT+?
The MAX6639EVKIT+ includes Windows 2000/XP/Vista (32-bit)-compatible GUI software (MAX6639.EXE) with menu-driven controls for reading/writing registers, real-time temperature and fan RPM display, data logging with timestamps, automatic polling (2Hz), and advanced SMBus/I²C command execution. Installation files (INSTALL.EXE, drivers, help PDF) are provided on the Maxim website.
