Maxim MAX1617 (sensor)

Added by ALMICO on 26 may 2001

The MAX1617 is a precise digital thermometer that reports the temperature of both a remote sensor and its own package. The remote sensor is a diode-connected transistor - typically a low-cost, easily mounted 2N3904 NPN type - that replaces conventional thermistors or thermocouples. Remote accuracy is +-3C for multiple transistor manufacturers, with no calibration needed. The remote channel can also measure the die temperature of other ICs, such as microprocessors, that contain an on-chip, diode-connected transistor. The 2-wire serial interface accepts standard System Management Bus (SMBus) Write Byte, Read Byte, Send Byte, and Receive Byte commands to program the alarm thresholds and to read temperature data. The data format is 7 bits plus sign, with each bit corresponding to 1C, in twos-complement format. Measurements can be done automatically and autonomously, with the conversion rate programmed by the user or programmed to operate in a single-shot mode. The adjustable rate allows the user to control the supply-current drain. The MAX1617 is available in a small, 16-pin QSOP surface- mount package.

For GF6600GT need to setup offset +21C of GPU. Ambient of GPU is all right.

Sensor Chip on my Nvidia FX5900XT. Speedfan's reading of GPU Core Temp is incorrect ... it shows remote temperature twice.

speedfan reports this as my NVIDIA Geforce5 5950 Chip but Temp is reported -16 degrees

temperature reading on eVGA 6800 GT is -26 core, but right on for ambient temp sensor.

To match the GPU Core temperature for the XFX 6800LE compared to RivaTuner, the offset of temp2 is 26 degrees
