MAX6680 - Fail-Safe Remote/Local Temperature Sensors

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.

Features

www.DataSheet4U.com 19-2305; Rev 0; 4/02 ±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 shutdown.
