EMC6D100/EMC6D101*

Environmental Monitoring

and Control Device with

Automatic Fan Capability

*NOTE: The EMC6D101 is not recommended for new designs.

The EMC6D102 Fan Control Device with Hardware

Monitoring and Acoustic Noise Reduction Features is the replacement device recommended for new designs.

The EMC6D100 & EMC6D101 monitor external voltages, temperatures, and fan speeds. They use this monitoring

capability to alert the system to out of limit conditions and can automatically control the speeds of multiple fans in a

PC or embedded system. The EMC6D101, available in a 24-pin SSOP package, and the EMC6D100, available in a

28-pin SSOP package, are designed to be register compatible. The EMC6D100 offers all the features of the

EMC6D101 plus additional voltage monitoring and system control features. The following is a summary of the

features offered in both packages:
