Data Brief
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 deltasigma ADC architecture provides superb linearity, high
accuracy, and excellent noise immunity.
