EMC1102
SST Compliant Hardware Monitor with Two Temperature Channels
General Description
The EMC1102 is a one-wire sensor that is capable of monitoring up to two temperature zones for an Intel PC platform containing an SST host. The two temperature
zones consist of an internal temperature diode and an externally connected temperature diode. 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.
