Description
EMC1152 SST Compliant Hardware Monitor with Two Temperature Channels and Five Voltage Channels
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. APPLICATIONS Desktop PCs, Servers and Workstations FEATURES
