PRODUCT FEATURES

General Description

The EMC2106 is an SMBus compliant fan controller with

up to five (up to 4 external and 1 internal) temperature

channels. The fan drivers can be operated using two

methods each with two modes. The methods include an

RPM based Fan Speed Control Algorithm and a direct

drive setting. The modes include manually programming

the desired settings or using the internal programmable

temperature look-up table to select the desired setting

based on measured temperature.

The temperature monitors offer 1°C accuracy (for

external diodes) with sophisticated features to reduce

errors introduced by series resistance and beta variation

of substrate thermal diode transistors commonly found

in processors.

The EMC2106 also includes a hardware programmable

temperature limit

output for thermal protection of critical circuitry.
