MAX6657/MAX6658/MAX6659
±1°C, SMBus-Compatible Remote/Local Temperature Sensors with Overtemperature Alarms
General Description
The MAX6657/MAX6658/MAX6659 are precise, twochannel digital temperature sensors.
Each accurately measures the temperature of its own die and one remote PN junction, and reports the temperature in digital form on a 2-wire serial interface.
The remote junction can be a diode-connected
transistor like the low-cost
NPN type 2N3904 or 2N3906
PNP type.
The remote junction can also be a common-collector
PNP, such as a substrate
PNP of a microprocessor.
The 2-wire serial interface accepts standard System Management Bus (SMBus™) commands such as Writ...
