EMC1133 SST Compliant Hardware Monitor with Three Temperature Channels and Three Voltage Channels PRODUCT FEATURES Data Brief General Description The EMC1133 is a one-wire sensor that is capable of monitoring up to three voltages and three temperature zones for an Intel PC platform containing an SST host. The three temperature zones consist of an internal temperature diode and two externally connected temperature diodes. In cooperation with a host device, thermal management and fan control can be performed. Communication takes place over a one-wire SST based interface. The internal 11-bit delta-sigma ADC architecture provides superb linearity, high accuracy, and excellent noise immunity. 0.125°C resolution ±1°C Accuracy (50°C to 70°C) Diode Fault Reporting Second External Diode configured to read a discrete diode.
