General Description

The EMC1103 is a one-wire sensor that is capable of

monitoring up to 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.
