±1°C Fail-Safe Remote/Local Temperature Sensors with SMBus Interface
General Description
The MAX6680/MAX6681 are precise, two-channel digital thermometers.
Each accurately measures the temperature of its own die and one remote PN junction and reports the temperature on a 2-wire serial interface.
The remote junction can be a diode-connected
transistor like the low-cost
NPN type 2N3904 or
PNP type 2N3906.
The remote junction can also be a commoncollector
PNP, such as a substrate
PNP of a microprocessor.
The MAX6680/MAX6681 include pin-programmable default temperature thresholds for the OVERT output, which provides fail-safe clock throttling or system ...
