MAX642

General Description

Features

The MAX6642 precise, two-channel digital temperature

sensor accurately measures the temperature of its own

die and a remote PN junction and reports the tempera-

ture 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.

o Dual Channel: Measures Remote and Local

Temperature

o +0.25°C Resolution

o High Accuracy 1°C (max) (Remote) and

2°C (Local) from +60°C to +100°C

o Measures Remote Temperature Up to +150°C

o Programmable Overtemperature Alarm

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 bit

with the least significant bit (LSB) corresponding to

+0.25°C. The ALERT output asserts when the local or

remote overtemperature thresholds are violated. A fault

queue may be used to prevent the ALERT output from

setting until two consecutive faults have been detected.

Measurements can be done autonomously or in a sin-

gle-shot mode.

Remote accuracy is 1°C maꢀimum error between

+60°C and +100°C. The MAX6642 operates from -40°C

to +125°C, and measures remote temperatures

between 0°C and +150°C. The MAX6642 is available in

a 6-pin TDFN package with an eꢀposed pad.
