MAX6642 ±1°C, SMBus-Compatible Remote/Local Temperature Sensor With Overtemperature Alarm

The MAX6642 is a precise, two-channel digital Temperature Sensor It accurately measures the temperature of its own die and a remote PN junction, and reports the temperature data over a 2-wire serial Interface The remote PN junction is typically a substrate PNP Transistor on the die of a CPU, ASIC GPU, or FPGA The remote PN junction CAN also be a Discrete diode-connected small-signal Transistor
The 2-wire serial Interface accepts standard system management bus (SMBus), Write Byte, Read Byte, Send Byte, and Receive Byte commands to read the temperature data and to program the alarm thresholds. To enhance system reliability, the MAX6642 includes an SMBus timeout. The temperature data format is 10 bits with the least significant bit (LSB) corresponding to +0.25C. The active-low ALERT output asserts when the local or remote overtemperature thresholds are violated. A fault queue CAN be used to prevent the ALERT-bar output from setting until two consecutive faults have been detected.
Measurements CAN be done autonomously or in a single-shot mode.
Remote accuracy is 1C maximum error between +60C and +100C. The MAX6642 operates from -40C to +125C, and measures remote temperatures between 0C and +150C. The MAX6642 is available in a 6-pin TDFN package.
