PRODUCT FEATURES
Datasheet
General Description
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.
The temperature monitors offer ±0.5°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 EMC2103 also includes a hardware programmable
temperature limit and dedicated system shutdown
output for thermal protection of critical circuitry.
