Microchip EMC1043 SMBus Temperature Sensor

Microchip EMC1043 SMBus Temperature Sensor

Microchip EMC1043 SMBus Temperature Sensor monitors three temperature zones, one internal diode and two externally connected diodes, for PC and embedded environments. The EMC1043 includes beta compensation circuitry to correct for variation in the beta of measurement transistors. Other extended features include resistance error correction and ideality factor configuration to eliminate major sources of temperature measurement error. An added feature to the EMC1043 is a function that automatically compares the two external temperature zones and reports the hotter of the two temperatures. Selectable conversion rates and standby mode support low-power operation. The temperature measurement ranges support data ranges (and formats), -64°C to +127°C and -64°C to +191°C.
