EMC2103
RPM-Based Fan Controller with
Hardware Thermal Shutdown
PRODUCT FEATURES Datasheet General Description Features The EMC2103 is an SMBus compliant fan controller with
up to up to 3 external and 1 internal temperature
channels. The fan driver can be operated using two
methods each with two modes. The methods include an
RPM based Fan Speed Control Algorithm and a direct
PWM 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. пЃ® The temperature monitors offer В±0.5В°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. — 4-wire fan compatible
— High and low frequency PWM
