Precision SMBus-Compatible Remote/Local Temperature Sensors with Overtemperature Alarms
General Description
The MAX6648/MAX6692 are precise, two-channel digital temperature sensors.
They accurately measure the temperature of their own die and a remote PN junction, and report the temperature in digital form using a 2-wire serial interface.
The remote PN junction is typically the emitter-base junction of a common-collector
PNP on a CPU, FPGA, or ASIC.
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.
