EMC2104 Dual RPM-Based PWM Fan
Controller with Hardware
Thermal Shutdown
PRODUCT FEATURES Datasheet General Description Features The EMC2104 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 1В°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. „ —
