PRODUCT FEATURES

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.
