The MAX6695/MAX6696 are precise, dual-remote, and local digital temperature sensors. They accurately measure the temperature of their own die and two remote diode-connected transistors, and report the temperature in digital form on a 2-wire serial interface. The remote diode is typically the emitter-base junction of a common-collector PNP on a CPU, FPGA, GPU, or ASIC.

The 2-wire serial interface accepts standard system management bus (SMBus) commands such as Write Byte, Read Byte, Send Byte, and Receive Byte to read the temperature data and program the alarm thresholds and conversion rate. The MAX6695/MAX6696 can function autonomously with a programmable conversion rate, which allows control of supply current and temperature update rate to match system needs. For conversion rates of 2Hz or less, the temperature is represented as 10 bits + sign with a resolution of +0.125°C. When the conversion rate is 4Hz, output data is 7 bits + sign with a resolution of +1°C. The MAX6695/MAX6696 also include an SMBus timeout feature to enhance system reliability.

Remote temperature sensing accuracy is ±1.5°C between +60°C and +100°C with no calibration needed. The MAX6695/MAX6696 measure temperatures from -40°C to +125°C. In addition to the SMBus active-low ALERT output, the MAX6695/MAX6696 feature two overtemperature limit indicators (active-low OT1 and active-low OT2), which are active only while the temperature is above the corresponding programmable temperature limits. The active-low OT1 and active-low OT2 outputs are typically used for fan control, clock throttling, or system shutdown.

The MAX6695 has a fixed SMBus address. The MAX6696 has nine different pin-selectable SMBus addresses. The MAX6695 is available in a 10-pin µMAX® and the MAX6696 is available in a 16-pin QSOP package. Both operate throughout the -40°C to +125°C temperature range.

Product Detail

The MAX6695 evaluation kit (EV kit) is an assembled and tested PC board with a mounted MAX6695. The EV kit allows full evaluation of the MAX6695 temperature sensor. The MAX6695 monitors its own die temperature and the junction temperature of two external diode-connected transistors. It converts the temperature to 11-bit, 2-wire serial data that can be accessed over a 2-wire serial bus.

The MAX6695 EV kit includes both external diode-connected transistors (2N3906) soldered to the board, which can be removed. The board can then be connected through a twisted pair to remote diodes close to your system.

The MAX6695 evaluation system consists of a Maxim command module (CMOD232) and a MAX6695 EV kit. The CMOD232 board connects to a computer's RS-232 serial port to provide a computer-controlled SMBus™/I²C bus. Windows® 95/98/2000/XP-compatible software provides a user-friendly interface to exercise the features of the MAX6695. The program is menu driven and offers a graphic interface with control buttons and status display.

Order the MAX6695EVCMOD2 for a complete PC-based evaluation of the MAX6695. Order the MAX6695EVKIT if you already have an SMBus interface.
