PRODUCT FEATURES
Data Brief
General Description
„
The EMC1152 is a one-wire sensor that is capable of
monitoring up to five voltages and 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.
