MAX1619 Remote/Local Temperature Sensor With Dual Alarm Outputs And SMBus Serial Interface

The MAX1619 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 two's 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 MAX1619 is nearly identical to the popular MAX1617A, with the additional feature of an overtemperature alarm output (active-low OVERT) that responds to the remote temperature; this is optimal for fan control.
