General Description
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.
FEATUREs
♦ Dual Channel: Measures Remote and Local Temperature
♦ +0.25°C Resolution
♦ High Accuracy ±1°C (max) (Remote) and ±2°C (Local) from +60°C to +100°C
♦ Measures Remote Temperature Up to +150°C
♦ Programmable Overtemperature Alarm Temperature Thresholds
♦ SMBus/I2CTM-Compatible Interface
♦ Tiny TDFN Package
