EMC1424

EMC1423/EMC1424 1°C Temperature Sensor with Hardware Thermal Shutdown PRODUCT FEATURES Datasheet General Description The EMC1423 and EMC1424 are high accuracy, low cost, System Management Bus (SMBus) temperature sensors. Advanced features such as Resistance Error Correction (REC), Beta Compensation (to support CPU diodes requiring the BJT/transistor model including 45nm, 65nm and 90nm processors) and automatic diode type detection combine to provide a robust solution for complex environmental monitoring applications. Additionally, the EMC1423 and EMC1424 provide a hardware programmable system shutdown feature that is programmed at part power-up via two pull-up resistor values and that cannot be masked or corrupted through the SMBus. Each device provides ±1° accuracy for external diode temperatures and ±2°C accuracy for the internal diode temperature. The EMC1423 monitors three temperature channels (two external and one internal). The EMC1424 monitors four temperature channels ...
